Description:Gloeoporus adustus (Fr.) Pilat
Atlas Champ. Europe ser. B. fase. 13-14 (1937) 157; Nuss, Biblioth. mycol. 45 (1975) 65 (temperate biology).
This common temperate fungus. generally known now as Bjerkandera adusta (Fr.) Karst., has many goud descriptions, but I give the following notes to assist comparison with the tropical G. nigrescens (p. 52).
Pores 120-190 µm wide, dissepiments 55-110 µm thick. (including the hymenium). Spores 4-5.5 x 2.5-3 µm, ellipsoid, shortly oblong. thin-walled, aguttate. Basidia 12-18 x 4.2-5.7 µm. clavate, nut guttulate; sterigmata 4. 2.5-3.5 µm long. Cystidia and hyphal pegs none. Hymenium continuous except at the sterile pure-edges, nut thickening; subhymenium very narrow, merely 1-2 hyphae thick. the hyphae 2-3 µm wide. Hyphae monomitic. clamped, 2.5-6 µm wide, walls 1-2 µm thick. cells 35-600 µm long. the larger hyphae radiating and sparsely branched, sometimes with fine secondary septa, the narrow hyphae more branched and often interweaving but nut forming binding hyphae, many of the hyphae finely guttulate especially in the dense tissue over the tubes. easily breaking at the septa on dissection; in the dissepiments 2-3.5 µm wide, walls -0.5 µm thick. descending, the walls becoming pale fuliginous but nut agglutinated, nut gelatinous, I-ve. Surface of pileus with a rather thin tomentum 200-500 µm thick. composed of branched hyphal ends 2-4 µm wide, hardly thick-walled, often agrregated in loose spicules and resembling sterile dissepiments.
The development of the fruit-body is described in detail by Kennedy and Larcade (Mycologia 63. 1971. 69-78).
