STUDIA BOTANICA HUNGARICA (Antea: Fragmenta Botanica) XVI. 1982 p. 49-52 Mycological examination of sawdust depots in Hungary II. By M. BABOS (Received November 17, 1981) Abstract: Two new fungi taxa from a mixture of rotten bark and sawdust are described: Pluteus aigroviridis sp.n. and Collybia distorta (Fr.) Quel . var.amara var.n. Pluteus nigroviridis Babos sp.n. (Figs. 2, 3) Pileus 3-5-8 cm latus; gibbosus-convexus, explanatus; metallice-nitidus, nigrescenti viridis; radialiter, minute obsite übrillosus. Lamellae e rosaceo in incarnatum transigentes. Stipes cylindricus, 4-6 x 0.5-1 cm, ad basim parum bulbosus (ad 1,4 cm); albidus, fibrillis nigrescentiviridibus ornatus, parte inferiori obscuro coerulescenti-viridis. Caro alba. Odore et sapore subnullo. Sporae ellipsoideae; 7-9.3-(10.9) x 5.4-6. 5-7 /im. Basidia cylindraceo-clavate, 4-sporigera. Cheilocystidia clavato-vesiculosa vel vesiculose-pedicellata; 31-62 x 10.9-18-(20)jum. Pleurocystidia metuloidea, partim cornigera (C-typus), partim ad M-typum pertinentia; 46-85 x 14-22 jum. Epicutis pilei cellulis hypharum apicalibus olivaceis; 80-210 x 12.4-20 jum; fibuligerae. Cellulae apicalis fusiformes (apice 4.7-9.3 .Aim lata) vel elongate clavata. Habit.: in silva frondosa, ad lignum putridum (ad corticum et scobi admixti). Typus: 72.880 in Herbario Musei Hist.-nat.Hung. , Budapest. Loc.: Uzsa (com. Veszprém), Hungária, 30 Oct. 1978, leg.: Babos - Bohus - Kustos - Rimőczi. Further herbarial data: same locality, 21 Oct. 1978, leg.: Babos - Friesz - Kustos (Herb. A. Friesz); 16 Sept. 1979, leg.: Babos. Pileus 8 cm in diameter (in subsequent gatherings smaller: (3) -5cm); obtusely umbonate-convex then expanded; when young concentrically wrinkled; blackish-green with a metallic lustre; with radially innate fibrillose structure. Lamellae free; up to 8 mm deep; turning to pale rose to flesh-colour. Stipe 4-6 x 0.5-1 cm; cylindrical, at the base slightly bulbous (to 1.4 cm height); white, with blackish-green fibrils, towards the base dark bluish-green. Flesh silky, white; soft in the pileus but fibrous in the stipe. Taste and smell is not characteristic. Spores ellipsoid; 7-9.3-(10.9) x 5.4-6.5-7 jum. Basidia cylindrical-clavate; 23-30 x 7-8.5jam; four-spored. Cheilocystidia thin-walled, clavate-vesiculose or vesiculose-pedicellate; 31-62 x 10.9-18-20jam. Pleurocystidia metuloid type (C and M type) but relatively thin-walled; 46-85 x 14-22 jum. (On the lamellae of the type-material - in consequence of juvenile stage - few C-type metuloid, possessing developed crown, could be seen, but on the lamellae of over-ripe specimens collected at the same place on 16 Sept. 1979, numerous C-type metuloids with well developed crown were found. The scanning electron micrographs were made from the type material, and the development of the crown is well demonstrated by them (Figs. 2, 3) ),The hyphae of the cuticle of the pileus with Part I appeared in Studia bot.hung,, 1981, 15: 33-46.
