Description:Inonotus glomeratus (Pk.) Murrill
Mycologia 12:18, 1920. - Polyporus glomeratus Pk., N.Y. State Mus. Ann. Rept. 24:78, 1872.
Basidiocarps effused-reflexed or resupinate, often effused for a distance of l-2 meters on fallen trees, pilei often imbricate, up to 4 x 10 x 1.5 cm, upper surface yellowish-brown, finely tomentose to glabrous, azonate, often covered with a bright golden yellow mass of basidiospores, margin concolorous or yellow to ochraceous, undulate, pore surface greyish brown, glancing, the pores angular, 3-5 per mm, with thin, tomentose dissepiments that become lacerate with age, context up to l cm thick, olden brown to dark yellowish brown, shiny on cut surfaces, fibrous-corky, faintly zonate, often with a hard, blackish upper layer, tube layer concolorous but separated by a darker layer, up to 7 mm thick, spore print bright golden yellow.
Hyphal system monomitic, generative hyphae pale yellowish brown in KOH, thin to thick-walled, rarely branched, 3-7 µm wide.
Setal hyphae dark reddish-brown in KOH, thick-walled, tapering to a point, unbranched, 7-12 µm in diam, setal hyphae more numerous and conspicuous in trama, projecting at dissepiment edges and often obliquely into the tubes, 250 to over 500 µm long, 10-15 µm in diam, clearly visible on broken tube surfaces under 30 x lens.
Hymenial setae abundant, subulate to ventricose, thick-walled, 16-28 x 5-9 µm.
Basidia ellipsoid, 4-sterigmate, 9-12 x 5-6 µm.
Basidiospores broadly ellipsoid to ovoid, pale yellowish, 5-7 x 4-5.5 µm.
