LICHEN GENUS MICAREA IN EUROPE 199 placed in Trapelia Choisy or Trapeliopsis Hertel & G. Schneider, or if a new genus is required to accommodate them. Lecidea littorella Nyl. in Flora, Jena 60: 229 (1877). - Catillaria littorella (Nyl.) Zahlbr., Cat. lich. univ. 4: 56 (1926). Type: Ireland, West Galway, 'Hibernia occidentalis, Bord du Lough Inagh, mais extremement rare', 1876, C. Larbalestier (Yi-^Yl. 18884- holotype!, isotypes: BM!, BM ex K!). The following notes were made from the holotype: Thallus saxicolous, not delimited but forming small patches amongst Hymenelia lacustris and Porina chlorotica, whitish, or dull ochraceous in part (? due to age), rimose, matt. Apothecia numerous, weakly marginate, plane to slightly convex, pallid to dull orange-red, 0-1-0-3 mm diam; margin not exceeding the level of the disc, very thin, c. 0-1-0-3 mm diam; margin not exceeding the level of the disc, very thin, c. 0-01-0-02 mm wide, whitish with faintly pruinose appearance. Hymenium 40-47 jxxn tall, hyaline. Asci cylindrical-clavate, ' Lecanora-type\ 8-spored. Spores ovoid to ovoid-oblong, often 'slipper-shaped', 1-septate and often constricted at the septum, 9-5-14(-16)x4-6(-7) ^tm (Fig. 56B). Paraphyses numerous, thin, 0-8-1 ixm wide, simple or sparingly branched below, becoming wider (to 1-7 ixm) and more frequently branched above. Hypothecium hyaline. Excipulum hyaline or dilute yellow-straw, inspersed with minute crystals in water mounts but ± clearing in K, c. 20 /am wide laterally, slightly widening below to 28 )u,m, minutely paraplechtenchymatous with cells in the lower part measuring 4—6x2-5^ /u,m. Pycnidia frequent, at first immersed, later becoming emergent, white (translucent when wet), c. 80-100 fxm diam. Conidia (Fig. 56C) simple, ovoid to pyriform, 2-8xl-5-l-7)Ltm. L. littorella was provisionally referred to Micarea by Kilias (1981: 392). However, my subsequent examination of the holotype proved it to be a saxicolous form of the normally foliicolous Catillaria bouteillei (Desm.) Zahlbr.; previous reports of this species on rock are given by Degelius (1944) and Santesson (1952). C. bouteillei is apparently widely distributed in Ireland, especially on the leaves oiBuxus (Knowles, 1929; Scannell, 1978). An additional British saxicolous specimen has been located: V.C.5, South Somerset, Broomfield, Ruborough Camp, 1914, W. Watson (BM ex K). Nylander's choice of the epithet 'littorella' is rather misleading because the holotype was not collected on the sea-shore, but on the shores of an inland, freshwater lake some 10 km from the sea. British authors (e.g. James, 1970; Fletcher, 1975) have mistakenly applied the name Catillaria littorella to a species that grows in crevices in siliceous rocks near the sea-shore; this species probably belongs to the perplexing Lecania ery5/fte complex. Lecidea milliaria a. [var.] terrestrisFr. Lich. Eur. 342 (1831). Type: not designated. This name is of unlikely appHcation in M/carea. Fries cited his L/c/i. Suec. no. 213, the example of which in UPS is a member of the Lecidea limosa group. Lecidea ocelliformis Nyl. in Flora, Jena 48: 145 (1865). - Bilimbia ocelliformis (Nyl.) Branth. & Rostr. in Bot. Tidskr. 3: 226 (1869). - Lecidea atroviridis f. ocelliformis (Nyl.) Hedl. in Bih. K. svenska VetenskAkad Handl. Ill, 18 (3): 64 (1892). - Catillaria prasina f. ocelliformis (Nyl.) Erichsen in Annls. mycol. 41: 205 (1943). Type: Finland, Tavastia australis, Hollola, ad corticem Sorbi, 30 vi 1863, /. P. Norrlin 210 (H-NYL 20607! - labelled Tsotype' by M. Inoue in 1979). This is not a Micarea. If the types of L. atroviridis (Arnold) Th. Fr. and L. ocelliformis are conspecific, as placed by Hedlund (op. cit.) and Vainio (1934: 218), then the latter epithet has priority. Lecidea pauxilla Krempelh. in Verh. zool.-bot. Ges. Wien 26: 455 (1876). Type: New Zealand, on bark [? Podocarpus], 18 -, C. Knight (M - lectotype!; M - isolectotype!). L. pauxilla was given as a synonym of Catillaria synothea (i.e. Micarea denigrata) by Zahlbruckner (Cat. lich. univ. 4: 78, 1926). However, the type material belongs to Cliostomum griffithii (Sm.) Coppins. Lecidea recondita Erichsen in Annls mycol. 42: 25 (1944). Type: Germany, Schleswig-Holstein: 'Apen- rade, an Blocken am Grunde einer Erosionsschluct im Geholz Jiirgensgaard' [now Denmark, Jylland, near Abenra], 28 vii 1932, C. F. E. Erichsen (HBG - holotype!). In the protologue Erichsen compares this with Lecidea sylvicola (= Micarea sylvicold). My examinations of the holotype proved it not to be a Micarea but referable to Catillaria chalybeia (Borrer) Massal.; see Kilias (1980: 448). Lecidea sabuletorum f. simp/icior Nyl., Lich. Scand.: 205 (1861). - Bilimbia trisepta f. simplicior (Nyl.) Vainio in Acta Soc. Fauna Fl. fenn. 53 (1): 258 (1922). Type: not designated. Nylander (loc. cit.) cited the following material 'supra muscos ad Helsingforse [ipse] et in Sueciae montibus [Thedenius] atque supra terram in Lapponia'. According to Fries (1874: 523) the 'Helsingforse' specimen is Lecidea verrucula (= Micarea turfosa); according to Vainio (1922: 140) the Swedish specimen from Funnesdalsberget in Harjedalen collected by
200 BRIAN JOHN COPPINS K. F. Thedenius is Lecidea dufourei (= Catillaria contristans (Nyl.) Zahlbr.). I am uncertain as to the identity of the specimen(s) referred to by Nylander as 'in Lapponia'. This may be based on the specimen cited by Vainio (1922: 140, 258) as 'supra Grimmias in Kipina Lapponiae a G. SeHn coUecta', which Vainio refers to Bilimbia trisepta [sensu Vainio = Micarea peliocarpa] f. simplicior. However, material in Nylander's herbarium (H-NYL 18841) labelled 'Lapponia, G. Selin 1861' is Catillaria contristans. Furthermore, another specimen of 'Lecidea sabuletorum f. simplicior' collected from Iceland by Isaac Carroll in 1861 (H-NYL 18862) is also C. contristans. It would appear that Nylander's concept of 'simplicior' is best fitted by C. contristans and should be typified on the material collected by Thedenius or Selin. Lichen niger Hudson, Fl. angl., ed. 2, 2: 524(1778). -Collemanigrum{Hudson)Y{offm. , Deutschl. Fl.: 103 (1796). - Micarea nigra (Hudson) Fr., Syst. orb.: 257 (1825). - Micarea nigra (Hudson) Fr., Stirp. agri femsion.: 37 (1825); comb, inval. (Arts 34.1, 43). - Placynthium nigrum (Hudson) Gray, Nat. Arr. Br. PI. 1:395(1821). This is the type species of the genus Placynthium Gray. Lichen viridescens Schrader, in Gmelin Syst. nat. 2 (2): 1361 (1792). - Lecidea viridescens (Schrader) Ach. Meth. Lich. : 62 (1803). - Micarea viridescens (Schrader) Brodo in Bryologist 70: 216 (1967). I have not seen the type of this name but if its normal interpretation is correct then the species belongs to the Lecidea granulosa group; see notes above under Lecidea gelatinosa. Micarea chrysophthalmaF . James in Lichenologist 5: 131 (1971). - Chrysothrix chrysophthalma (P. James) P. James & Laundon, in Laundon in Lichenologist 13: 104 (1981). This is a species of Chrysothrix and is discussed in detail by Laundon (1981). Micarea coccinea Fr., Syst. orb. : 257 (1825); nom. nudum (Art. 32.1). I do not know the identity of this species, and I have not seen this name in any other publication. On morphological grounds it is unlikely that Fries intended a new combination based on Lichen coccineus Dickson [= Haematomma ochroleucum (Necker) Laundon] or Lecidea coccinea Schw. [= Lecidea russula Ach.]. Micarea cyanescens Poelt & Dobbeler in Bot. Jb 96: 339 (1975). Holotype: Germany, Bayern, Altbayerische Alpen, Chiemgauer Berge, 900-1000 m on Campylium halleri on north-facing calcareous rocks, 29 ix 1974, /. Poelt (GZU, not seen). Paratypes: Austria, Tirol, Lechtaler Alpen, 'unteres Medriol-Tal uber Zams bei Landeck, an Dolomitblocken unter Griinerlen', 1600-1700 m, on Campylium halleri, 1969, J. Poelt (hb Poelt 13295!); Austria, Steiermark, 'uber Kalk, Rote Wand bei Mixnitz, c. 1470 m, unweit des Gipfels', 1974, J. Poelt (GZU!). This is a very curious species; its hymenium components are embedded in a dense gel which does not disperse in 50% of KOH. It is not a Micarea and a new genus is probably required to accommodate it. Micarea hylocomii Poelt & Dobbler in Bot. Jb. 96: 341 (1975). Type: Austria, Tirol, Samnaun Gruppe, on the way from Serfaus to Madatschen, c. 1500 m, on Hylocomium splendens, 15 ix 1972, J. Poelt (GZU - holotype!). I endorse the describing authors' view that the position of this species in Micarea is doubtful, and I beheve a new genus should be erected to accommodate it. Micarea leprosa P. James in Lichenologist 5: 133 (1971). - Vezdaea leprosa (P. James) Vezda, in Poelt & Dobbeler in Lichenologist 9: 170 (1977). This is a species of Vezdaea (Poelt & Dobbeler, 1975). A large collection of it from Scotland has recently been distributed as Hertel Lecid. Exs. 60. Micarea minima Poelt & Dobbeler in Bot. Jb. 96: 342 (1975). Holotype: Germany, Rheinland-Pfalz, 'Boschung eines Waldweges bei Battweiler, Kreis Zweibriicken, c. 400 m', on Polytrichum commune and P. formosum, 1974, J. Poelt (GZU, not seen). Paratype: Austria, Karnten, Nockgruppe, Afritzer Berge, 'Bergwald und saure Weiden iiber Verditz, nordlich Villach', c. 1300 m, on Polytrichum formosum, 1974,/. Poe/f (hb Poelt 13294!). I was unable to find any apothecia in the examined paratype and so I cannot confidently exclude this species from Micarea. Further studies are required to establish its generic disposition. Patellaria nigrataMuW. Arg. in Flora, Jena7l: 540(18SS).-Bacidianigrata{Mu\\. Arg.) Zahlbr., Car. lich. univ. 4: 129 (1926). - Micarea nigrata (Miill. Arg.) Kalb, Lichenes Neotropici Fasc. 1: 8 (1981); comb, inval. (Art. 33.2). Type: Brazil, Apiahy, on argillaceous soil, 1883, Puiggari (G!). This species closely resembles a Micarea and even appears to have 'micareoid' algae. However, its
