NMFS is also charged with the development and implementation of policies for managing national fishing grounds, development and enforcement of domestic fisheries regulations, surveillance of foreign fishing off United States coastal waters, and the development and enforcement of international fishery agreements and policies. NMFS also assists the fishing industry through marketing service and economic analysis programs, and mortgage insurance and vessel construc- tion subsidies. It collects, analyzes, and publishes statistics on vanous phases of the industry The NOAA Technical Report NMFS Circular series continues a series that has been in existence since 1941 . The Circulars are technical publications of general interest intended to aid conservation and management. Publications that review in considerable detail and at a high technical level certain broad areas of research appear in this series. Technical papers originating m economics studies and from management investigations appear in the Circular series. NOAA Technical Report NMFS Circulars are available free in limited numbers to governmental agencies, both Federal and State They are also available in exchange for other scientific and technical publications in the marine sciences Individual copies may be obtained (unless otherwise noted) from D822, User Services Branch, Environmental Science Information Center, NOAA, Rockville, MD 20852 Recent Circulars are; 418.

Gordon, Assistant Administrator for Fisheries FOREWORD This NMFS Circular is part of the subsenes "Manne Flora and Fauna of the Northeastern United Stales." which consists of original, illustrated, modern manuals on the identification, classification, and general biology of the estuanne and coastal manne plants and animals of the northeastern United Slates. The manuals are published at irregular intervals on as many taxaof the region as there are specialists avail- able to collaborate in their preparation Geographic coverage of the "Manne Flora and Fauna of the Northeastern United States" is planned to include organisms from the headwaters of estuanes seaward to approximately the 200 m depth on the con- tinental shelf from Maine to Virginia, but may vary somewhat with each major taxon and the interests of collaborators. Whenever possible representative specimens dealt with in the manuals are deposited in the reference collections of major museums of the region. The "Manne Flora and Fauna of the Northeastern United States" is being prepared in collaboration with systematic specialists in the United States and abroad. Each manual is based pnmanly on recent and ongoing revisionary systematic research and a fresh examinatin of the plants and animals. Each major ta.xon. treated in a separate manual, includes an introduction, illustrated glossary, uniform originally illus- trated keys, annotated checklist with information when available on distribution, habitat, life history, and related biology, references to the major literature of the group, and a systematic index. These manuals are intended for use by biology students, biologists, biological oceanographers. informed laymen, and others wishing to identify coastal organisms for this region. Often they can serve as guides to additional information about species or groups. The manuals are an outgrowth of the widely used "Keys to Manne Invertebrates of the Woods Hole Region." edited by R. I. Smith in 1964. and produced under the auspices of the Systematics Ecology Pro- gram. Marine Biological Laboratory. Woods Hole. Mass. After a sufficient number of manuals of related taxonomic groups have been published, the manuals will be revised, grouped, and issued as special vol- umes, which will consist of compilations tor phyla or groups of phyla.

Marine Flora and Fauna of the Northeastern United States. Lichens (Ascomycetes) of the Intertidal Region RONALD M.TAYLOR' ABSTRACT Thi> manual ircals (he lichens lound in ihc intertidal region trom New Jersey to Newloundland Methods of collection, preparation, and study are briefly treated. Twenty-two species are covered, both in an illustrated key and an alphabetical listing, witfi brief descriptions and notes on ecology and dislribution. A glossary of terms is included INTRODUCTION METHODS OF COLLECTION AND STUDYING The content and style of this paper are intended to encourage and serve all who might wish to study the lichens of the fascinating and complex marine littoral environment. It is evident from the lit- erature and from inquines directed to the author that the manne lichen flora presents an interesting enigma to biologists of diverse disciplines. It is hoped that this paper will help them in studying, recognizing, and accurately reporting the lichens of the littoral zone. A lichen is not "a plant" but rather a life tribution of Verrucaria erichsenii. <- ahrs enrs 12hrs 20hr5 24hrs Figure 2. — Vertical divlribulion of \'erriuaria degelii.

Due to the great vanation in the distance between mean low tide and mean high tide (ca. 1 to 10 m). the dis- tance below high tide is given in hours of submergence. Each inter- val on the X-axis represents 10% of the total collections of that species by the author In each figure the graph on the right repre- sents the vertical distnbution on exposed shores and the graph on the left represents the vertical distribution on sheltered shores.

ILLUSTRATED KEY TO SPECIES The key is based primarily on charactenstics that can be observed with a dissecting microscope at 20 x magnification; in some cases observation of spores with a compound microscope may be required. The vertical sections of perithecia of Verrucaria species illustrated in the key are typical sections. Because of the extreme degree of variation of species of manne lichens (especially of Verrucaria). identification of species from the key alone should be regarded as tentative until the more detailed descnption in the Annotated List of Species is read. Five species from the Canadian Maritime Provinces are included even though at present they are not known from the eastern United States. At least one species. Verrucaria maura. has not been collected in the eastern United States recently but the author has seen specimens collected from the area over 50 yr ago. 1 Thallus foliose (Fig. 9); always orange and KOH + purple 2 1 Thallus crustose (Fig. 10) only in a few species orange and KOH + purple 4 1 Thallus erect, fruticose, composed pnmanly of algal (Caloihnx) filaments; ascocarp penthecioid (Fig. II) Lichina conjinis Figure \\.— Lichina confinis.

Cherbourg 5:212. 1857. DESCRIPTION: Thallus epilithic (siliceous rock), endolithic (calcareous rock and shells), yellowish if epilithic, greyish or blackish-brown if endolithic. Perithecium almost wholly immersed in substrate or sessile with black hemispherical to broadly conical involucrellum, 0.15 to 0.5 mm diameter, excipulum colorless to pale brown. Spores eight perascus. ovoid, two-celled, one cell usu- ally broader than the other. 9-20 x 4-7.5;(m.

Genus Verntcaria The species of this genus form crusts which may be contmuous or form scattered patches, rimose areolate or divided into discrete are- oles or lobes. The thalli vary in thickness from 20 to 500/jm, and may be almost completely transparent to entirely opaque. In some species, the transparency of the thallus may be enhanced by wet- ting, while others remain opaque when wet. The thalli may be smooth or roughened by dark points or ridges. The ridges, called juga (Santesson 1939), vary in length, width, and thickness. The exact ongin and ontogeny of the juga is not known but it appears that they originate at or just below the surface of the thallus. In the author's experience, they do not extend to the substrate except at the edges of the areoles. Often a distinction is made in keys between point and ridge forms of the juga, but it is common that the points are merely peaks on inconspicuous or hidden ridges. The perithecia of all of the littoral Verrucariae, with which the author has worked, have a dark involucrellum which may spread widely or be closely appressed to the excipulum. This darkening may extend into the lower excipulum, terminating a short distance below the involucrellum proper or it may not extend into the lower excipulum. The darkening may occur intermittently or continu- ously throughout the lower excipulum. This darkening is given considerable taxonomic importance by Servit ( 1954) and by Ench- sen (1957) but Swin.scow ( 1965) discounted this importance on the grounds that it is highly variable within a species. The author con- curs with Swinscow in this view. Perithecial size is not, in itself, very useful in distinguishing species. Perithecium diameters vary generally between 0.05 and 0.7 mm and these dimensions overlap considerably between Verrucaria species. Although vertical sec- tions are illustrated in the key. none is claimed to be typical for then; is much variation in many, if not all species. Santesson (1939) has noted the high variability of spore size in littoral pyrcnolichens and suggested that they should not be given great taxonomic importance. All spores in yernicariti are simple and hyaline. For the most part, the spores are thin walled and of similar size, occurring eight per ascus. Verrucaria inlernigrescens and V silicicola are the notable exceptions to the above in north- eastern North America. The spores of V. inlernigrescens are thick walled and those of V. silicicola are unusually large. The remainder are ovoid to reniform and exhibit overiapping size ranges between species, Verrucaria amphibia R. Clem. Ess. Var Veg. Andalucia 299. 1807. DESCRIPTION: Thallus continuous to rimose areolate. black when dry. translucent green to amber when wet, with irregular black ndges often enclosing lenticular areas 50-l(X)/im thick. Perithecia large (13-16 mm), prominently elevated, often flattened or concave on top. vertical and horizontal ridges forming reticular pattern, lenticular areas often enclosed by ridges at base; excipu- lum hyaline to partly darkened below. Spores hyaline, ovoid. 7-19 X 4-7. 5^m. This species might readily be confused with V. maura. Both spe- cies have dark thalli with juga forming pegs or ridges and with robust penthecia. However, they are easily distinguished on closer examination. Whereas V. maura tends to have points raised above the thallus, V. amphibia tends toward ridges. The ridges tend to enclose lenticular areas on a dry thallus giving the impression of ripples on water When wet. V. amphibia becomes more translucent and light colored against which the black ridges become contrasted. The thallus of V. maura remains dark when wet except on very thin juvenile specimens. The thallus of V. amphibia tends to be continu- ous whereas that of V. maura tends to be rimose areolate but in nei- ther case are the characters absolute. Areolation appears to develop and increase with age in V. amphibia. Verrucaria amphibia pro- duces large, steep sided perithecia often strongly depressed on top. a form also produced in some instances by V maura. Such perithe- cia of V. amphibia have two characteristics not demonstrated by V. maura: whereas V. maura may have many fine points or pegs cov- ering the perithecium. the design on V amphibia is a reticulum of vertical and horizontal ridges. Also, where the V amphibia perithe- cium meets the thallus, the ridges tend to enclose areas of ovoid shape and appear light and translucent when wet (see the Key). Verrucaria amphibia is little discussed in literature. Santesson- says that it is not known from Scandinavia, although it occurs in England. Ferry and Sheard (1969) included V amphibia in their key but did not deal with it in detail . The author first became acquainted with It by examining herbanum specimens and his measurements should not be regarded as limits due to the small amount of material examined. There is no prior report of this species from North Amenca. GENERAL DISTRIBUTION: England (Ferty and Sheard 1969). Wales (Fletcher 197.3a). Germany (Ullnch MSC).

Verrucaha ceuihocarpa is easily confused with Verrucariu tlege- lii when either is modified by environment or when its structure is obscured by epiphytic algae. The clefts of V. cethocarpa may become darkened and. on cursory examination, may resemble the dark ridged border of areoles of V. degetii. Careful examination is needed to observe the absence of ridges. Conversely sometimes the ridges are scant on a thallus of V. degelii and it may by mistaken for that of V. ceulhncarpu . Perhaps the greatest obstacle to correct identification is obscur- ing of surface detail by epiphytic algae. Portions of questionable thalli should be flooded with water to soften and expand the algae. If details are still obscured, the flooded portion can be scrubbed with a small water color brush. True ndges are fairly resistant to such gentle abrasion and will persist until the thallus becomes too .softened by the water to maintain its integrity. According to Santessons key (1939), the pnme diagnostic feature of k' degelii vs. V ceuthocarpa is the presence of ridges on V. degelii. The author finds that two other features are quite useful. The best of the two is tendency for tlatness to concavity between ndges of an areole of V. degelii compared with the convexness of areoles and branches thereof in V ceiilhocarpa. Verntcaria ceulhoearpii is truly glabrous. Further, from the limited material in the authors three North American collections it also appears that the involucrellum of V ceuthocarjxi tends to be brown whereas that of V. degelii is dis- tinctly black.

On the other hand, a growth of dark algae on V ceuthoearpa, especially when dry, may obscure the color and glabrous nature of the thallus and give the illusion of ndges on the edge of areoles. One cannot (wer-emphasize the importance of detecting and removing such epiphytic algae! The thallus of V. degelii varies greatly in thickness and transpar- ency depending on age or extent of development. It is almost always areolate. with only one known exception. In that case, a rather large area of smooth, continuous thallus was surrounded by a raised black ndge and a crack, also bordered by a black raised ridge, extended inward t(iward the center At the edges of this patch of thallus was more thallus divided into typical discrete areoles with similar black borders. More commonly a young thallus is thin, nearly transparent, smooth and brown to tan. It is areolate and is often divided into lobes by a dendntic pattern of grooves. In such a thallus. the grooves are usually hyaline. The ontogeny of these lichens has not been studied and must be inferred from observations of what could as easily be the results of conditionsof growth as of aging. It appears, however, that older thalli thicken and develop discrete areoles, usually with black borders and frequently with black lines connecting them with the pentheciuni. These areas of blackness then seem to proliferate under some condi- tions to produce unelevated patterns or raised juga. Sometimes the black area extends beneath the perithecium and sometimes it docs not. The penthecium is commonly immersed, with or without raised ndges aniund the ostiole. At times there is a convex area raised around the o.stiole. The author has seen prominently raised convex perithecia on the same thallus as sunken perithecia. The degree of penthecial elevation appears to be a vanable character of the species. Spores are ovoid but sometimes pointed when young. A clear spot commonly, although not always, appears in the center of the younger spores. Sanlesson (1939) reported the range of spore sizes for Verru- cariu degelii as 10-13 '■ 5-6/im. which is consistent with that observed by the author GENERAL DISTRIBUTION: NORWAY (Santesson 1939).

Though published in 1*^39. this species was known only from Nor- way until the author's collections, thus there are few specimens and little study of ecology upon which to base conclusions about environ- mental intlucnces on variations. It is reasonable to assume, however, that the nature of variations is consistent with that seen in other Vemi- canae. If so. color wduUl he lighter in shade forms than sun lorms and ndges would be fewer and thinner in shade forms than on sun forms. This kind of variation is probably the cause of confusion o\ some specimens of V degelii with V ceiilhocarpa . The identity of a robust .specimen of V degelii is beautifully clear. However, the ridges may become scant and the specimen strongly resembles the morpho- lype of V ceutluKurjui with darkened clefts between areoles.

In bnght light the thallus is dark olive and if grown in the shade it is a very light olive green. It usually is rather transparent to translucent. The transparency is increased by wetting upon examination. Short, mostly straight ndges are charactenstic on the thallus. These become reduced in size and frequency in the shade modification.

Typi- cally this is so but it is not uncommon to find a thallus of V. erichsenii continuous in an especially wet environment, where the thallus becomes thick and gelatinous. When dry the thallus is usu- ally blackish-brown to black, A grey morphotype with a texture like that of graphite was collected in the Narragan.sett Bay area. When moistened during examination the thallus increased in trans- parency, one of the best tests of questionable thalli. When wetted they reveal a pattern of black markings typical of the pattern of ridges usually seen above the surface. The thallus of V. erichsenii typically has short, often branched irregular ridges or rows of points, frequently confluent with or continuing up over the penthe- cia. Ridges are longer than wide and rarely very high. In extreme circumstances ridges become higher and sharper forming cusps and aretes. In other extremes they may be immersed within the thallus to be revealed only by wetting. The most consistent character of the penthecium appears to be the irregular spreading base which seems most pronounced when viewed from above a wet thallus or when the thallus has been peeled from the rock and placed on a slide and illuminated from below. The diameters of penthecia tend to fall between 0. 1 and 0.3 mm. Zschacke (1934) and Enchsen ( 1957) both list a spore range of 8- 12 X 5-7;(m which agrees with the author's observations.

The author can add little to the descnption of variation provided by Santesson (footnote 2) and would like here to merely record his concurrence and quote Santesson's description (the material quoted was provided for the author in Swedish by Santesson) of typical V nuiiira as ; " 1 .

A common variation results from frequent washing with water from rain or waves which causes the thallus color and texture to become obscured by epithallic algae which produce a smooth greenish surface.

Erichsen (1957) recognized a var laetevirens as characterized by a leek green thallus which is less transparent. The author has also observed this in material from the southern part of its range in North America as well as a dark grey thallus in the same area. The dark grey thallus has a color and texture resembling graphite used in pencils. Upon wetting, the dark color disappears. The penthecia are brown to black and may be shiny or dull. Their shape may range from that of a slightly arched dome to more nearly hemispherical and pointed. The diameter of the perithecia is reported as 0.15-0.25 mm (Lamb 1953). 0.1-0.3 mm (Santesson footnote 2), 0.2-0.3 mm (Zschacke 1925). and 0.2-0.3 mm ( Erich- sen 1957). Erich.sen ( 1957) also recognized xar friesiaca as having a smaller perithecia of only 0.1-1.15 mm diameter The author measured 230 penthecia (10 each from 23 specimens) and found a range of 0.08-0.28 mm except for a single collection in which the range was 0. 16-0.48 mm with 4 out of 10 exceeding 0.3 mm. In no other collection did the diameter exceed 0.3 mm. Clusters of small or larger perithecia may be found and due to the normal patchy appearance of the thalli. one may be tempted to consider such patches as distinct species. Penthecium size should not be consid- ered of taxonomic significance in this species. Spores of V microspora are thin walled and will change shape somewhat with osmotic changes. Generally they are ovoid to slightly reniform. The species name infers smallness of spores, but this is not noticeably different from I' ditnuirsua and V sirUituUi. Spore sizes have been reported as 7-12 x 4-5//m (Lamb 1953), 7-11 x 5-7;(ni (Zschacke 1925), and 7-11 x 4-5fim (Erichsen 1957). Enchsen (1957) also recognized var mucosula Sands, with spores 5-9 x 4- 9;im, The author's spore measurements give a range of 6-11 x 3- 5;(m.

The thallus becomes translucent to quite transparent when DESCRIPTION: Thallus grass green to blackish-green, smooth and tough, continuous, often with necral cracks in herbanum speci- mens, 130-150 ;im thick, usually opaque (wet ordry); juga absent; prothallus. is present, whitish. Penthecia submerged to slightly raised, sometimes with prominent ostioles surrounded by chimney, excipulum clear below, involucrellum 0.05-0.2 mm diameter Spores simple, coloriess. usually ovoid. 8-11 ^ 4-5 /im. Thallus of this species is easily recognized in the field or in the herbarium. In old herbanum specimens it is brown. Upon drying it develops cracks that arc stnctly necral artifacts not to be confused w ith the nmose areolation typical of V. maiira. A whitish prothallus is often seen around a thallus on smooth rock. Perithecia arc normall) flush to slightly raised or sunken. When ripe, the nnolucrellum tends to cvaginate somewhat presenting a 20 conspicuous ostiole with a short chimney around it. One often sees whitish pits in the thallus which are the remains of old penthecia divested of their involucrella. The thallus of V mucosu is quite aggressive and often grows over crustose algae, such as Hildcnhruntia and Lithorhamiiia. It also is commonly found growing over other Vermcanae where the penthe- cia of the overgrown material project through the thallus of I' iimaisci causing a potential source of misidentification. Spores of V mucosa are not distinctive m either shape or size, San- tesson (1939) reported the size of spores to be highly vanable. 7-15 X 4-8/im. Pycnidia are quite common on V' iimcosci thalli. They appear as slits ringed with brown and occur widely scattered or in clusters. It is not uncommon to find mounds made up of aggregated pycnidia. GENERAL DISTRIBUTION: Sweden. Norway.

NEWFOUNDLAND: Northern Peninsula Section. East Coast Section. Avalon Section. Vcnucana .siruiiuUi is most noted for the strikingly large carbo- naceous structures termed juga by Santesson ( 1939). The juga rise above the thallus and tend to be broad and often branched. They commonly encompass a perithecium. Near the edge of the thallus they often radiate out from the center, marking the leading edge of thallus lobes. They are different from the ridges of I' cnchsenii and V. ditmarsica. being more like flattened plateaus and buttes than narrow ridges. The thallus is normally a bnght green when fresh but darkens in more intense sunlight. It fades quickly in the shade. In the herbar- ium the thallus soon becomes colorless and scarcely visible, a con- dition causing early workers to think that the juga were the entire thallus (Santes.son 1939). The thallus is continuous but often shows necral cracks upon drying. The penthecia are often amorphous, coalescing v\ith juga or appeanng as spheres frequently with flattened tops. The perithecia often are cracked or dissected and usually a shiny black. In the shade inodification the perithecia become more nearly spherical or may be elongated vertically. Juga become reduced, causing the shade modification of V. sihatula to resemble V. ditmar- sica. However, even in the shade modification, juga usually retain their flatness and are reduced in size, but still are broad by compari- son w ith other ridged species. Perithecium diameters are in the gen- eral range of 0.05-0.3 mm. Zschucke ( 1934) listed the spore range as 8-12 X 4-5;im and Enchsen ( 1957) as 8-1 1 x 4-5^m. GENERAL DISTRIBUTION: Sweden. Norway.

Spores hyaline. 18-22 x 8-9,(111. The author's knowledge of this species is limited to the examina- tion of available herbanum specimens collected and known only from Long Island. N.Y. The material seen resembled V microspora to a considerable degree. The thallus was brownish and patchy. The penthecia. for the most part, were shallow domes. Hednck (1933) gave 0. 15-0.4 mm as the diameter of penthecia and those seen by the author fell within this range. The salient charactenstic of this species is the spore size, listed by Hedrick (1933) as 19-22 x 8- 9^m. The author was unable to find spores but Brodo (1968) reported the range as 16-25 x 6-l0,(iii.

The Candelariae are KOH- and the spores are not polanlocular There is also a resemblance between Xanthoria candelaria and X. fallax when the latter displays lobe widths at the narrow end of the range for that species. However, in such a case the location of soredia will distinguish them. In X. candelaria the soredia are apical or lami- nal as opposed to the labrose mode in X. fallax.

The Board established the format for the "Manne Flora and Fauna of the Northeastern United Stales," invites systematists to collaborate in the preparation of manuals, reviews manuscnpts, and advises the Scientific Editor of the National Manne Fishenes Service. Thanks are expressed to Henry A, Imshaug for his assistance in research and advice in prepanng the manuscript. Thanks are also expressed to Melbourne R. Camker for continued assistance in later research stages and manuscript preparation. Richard D. Wood was very helpful in the field work in the Narragansett Bay area. Helen S. Taylor, Brian M. Taylor, and Sheryl M. Taylor contnbuled both in the research for and preparation of the mauscnpt. Adele Denison and Ralph Gorton aided in the preparation of the final manuscnpt. 25 COORDINATING EDITOR'S COMMENTS Publication of the "Maiine Flora and Fauna of the Northeastern United Stales" is most timely in view of the growing univeral emphasis on environ- mental work and the urgent need for more precise and complete identifica- tion of coastal organisms than has been available. It is mandatory, wherever possible, that organisms be identified accurately to species Accurate scien- tific names unlock the great quantities of biological information stored in libraries, obviate duplication of research already done, and often make pos- sible predlctionof attributes of organisms ihat have been inadequately stud- ied. Ronald Taylor started his research on lichens in l%4 at Michigan State University where he later received his doctoral degree. He was then, and is now, on the faculty of Lansing Community College at Lansing, Mich. Preparation of this manual was supported in part by a grant from the Environmental Protection Agency to the Edilonal Board of the "Marine Flora and Fauna of the Northeastern United States."
