Description:Albatrellus pes-caprae (Pers.:Fr.) Pouz. - Folia Geobot. Phytotaxon. 1:357, 1966. - Polyporus pes-caprae Pers.: Fr.. Syst. Mycol. 1:354, 1821. -Polyporus pes-caprae Pers., Traite Champ. Comest., p. 241. 1819. Basidiocarps annual. stipitate; stipe simple or branched. eccentric to lateral. cylindric or enlarged at the base, pale buff or with spots staining darker brown to reddish-brown, glabrous to faintly squamulose, appearing reticulate on the underside from poorly developed decurrent tubes, up to 8 cm long and 6 cm in diam; pilei solitary or several on a branching stipe, circular to reniform or irregular in shape. up to 20 cm wide: upper surface brown. with small scales 1-2 mm wide and composed of erect. loose clumps of hyphae; pore surface yellowish-cream to pinkish when fresh. pale brownish when dry. pores angular. hexagonal in appearance. mostly 1-2 per mm but some up to 2 mm in diam, with thin, lacerate dissepiments; context cream-coloured, firm-fibrous when dry, azonate. up to 2 cm thick; tube layer pale brownish. up to 3 mm thick.
Hyphal system monomitic; contextual hyphae hyaline in KOH. thin-walled and usually much collapsed. apparently often branched, with clamps and simple septa, 4-14 µm in diam; tramal hyphae similar; hyphae of pileus surface scales often with thickened walls, with cylindric to clavate apices. 5-16 µm in diam, with conspicuous clamps, negative in Melzer's reagent; gloeoplerous hyphae present.
Cystidia or other sterile hymenial structures absent.
Basidia clavate, 4-sterigmate, 30-55 x 8-12 µm. with a basal clamp.
Basidiospores broadly ellipsoid, conspicuously apiculate, hyaline, smooth. negative in Melzer's reagent, 8-11 x 6-8 µm.
Type of rot. Terrestrial, apparently not a wood-rotting fungus.
Cultural characteristics. Unknown.
Sexuality. Unknown.
Substrata. On soil, associated with conifers especially Pinus, exceptionally also recorded in association with Fagus in the Alps and the Carpathian mountains. In North America also seen in association with Juglans.
Distribution. Rare and scattered through Central and Southern Europe. north to Denmark (one locality) and not known from England and the Fennoscandian peninsula. Rare from eastern to western North America, also known from East Asia.
