Description:Albatrellus pes-caprae (Pers.:Fr.) Pouzar, 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, laterally stipitate, solitary to caespitose; pilei circular to reniform or irregular in shape, up to 12 cm wide; pilear surface reddish brown, with scales 1-2 mm wide composed of erect hyphae; stipe eccentric to lateral, cylindrical or bulbous 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 6 cm long and 3 cm wide; pore surface yellowish-cream to pinkish when fresh, yellowish when touched and pale brownish when dry, pores angular to hexagonal, mostly 1-2 per mm but some up to 2 mm wide, with thin, lacerate dissepiments, tubes pale brownish, up to 3 mm long; context cream-coloured, firm-fibrous when dry, azonate, up to 2 cm thick. Hyphal system monomitic; generative hyphae with clamps and simple septa, hyaline, thin-walled and usually much collapsed, often branched, 4-14 µm wide; hyphae of pilear surface scales often thick-walled, with cylindrical to clavate apices, 5-16 µm wide, with conspicuous clamps; gloeopleurous hyphae present. Basidia clavate, 30-55 x 8-12 µm, with four sterigmata.
Basidiospores broadly ellipsoid to amygdaliform, conspicuously apiculate, negative in Melzer's reagent, 8-11 x 6-8 µm.
