Index Fungorum number: IF828730; Faces of Fungi number: FoF09464
Basidiomata annual, small to medium sized, usually in clusters, soft and coriaceous when fresh, becoming harder on drying, light in weight, effused reflexed. Pileus 26-48 mm long, 20-35 mm wide, 3-5 mm thick, sessile, circular to irregular, covering the host, applanate, concentric zonations absent, irregularly wrinkled, glabrous, creamish white, light brown on bruising, tissue more brownish in KOH, margin even to slightly wavy. Hymenium poroid. Pores 4-6 per mm, round to slightly angular, oblique towards attachment region, cream, turning light brown on bruising, tubes up to 3 mm long, concolourous with pore surface. Context 1.5-2 mm thick, creamish white, homogenous. Odour not distinctive.
Hyphal system trimitic, generative hyphae with clamp-connections, skeletal hyphae thick-walled, unbranched and binding hyphae thick-walled and frequently branched. Pileipellis interwoven at base and forming an irregular cutis made of hyphae that are 2-3 μm wide, hyaline, slightly (up to 1 μm) thick to thick-walled. Pileal trama interwoven, generative hyphae 2-4 μm wide, hyaline, smooth, thin to slightly (up to 1 μm) thick-walled, branched, with clamp-connections. Skeletal hyphae 2-5 μm wide, hyaline, weakly dextrinoid in Melzer's reagent, thick-walled (1 μm), unbranched, septations not observed. Binding hyphae 1.5-2 μm wide, hyaline, weakly dextrinoid in Melzer's reagent, thick-walled (1 μm), highly branched, septations not observed. Hymenial trama interwoven, generative hyphae 2-4 μm wide, hyaline, smooth, thin to slightly (up to 1 μm) thick-walled, branched, with clamp-connections. Skeletal hyphae 2-4.5 μm wide, hyaline, weakly dextrinoid in Melzer's reagent, thick-walled, unbranched, septations not observed. Binding hyphae 1.5-2 μm wide, hyaline, weakly dextrinoid in Melzer's reagent, thick-walled (1 μm), highly branched, branches short, septations not observed. Cystidia absent. Mature basidia not observed. Basidiospores 5.5-8 × 2-2.5 μm, L = 7 μm, W = 2.1 μm, Q = 2.6-4, Qm = 3.36, cylindrical to allantoid, hyaline, smooth, thin-walled, sometimes monoguttulate, inamyloid in Melzer's reagent, acyanophilous in cotton blue.

Basidiomata annual, small, in clusters, imbricate, soft, membraneous and coriaceous when fresh, becoming hard upon drying, light in weight, effused reflexed. Pileus 4-12 mm long, 6-50 mm wide. 2-3 mm thick, sessile, applanate to uneven, semicircular, concentric zonations absent, glabrous to hispid, white, pale brown on bruising, margin thin, undulate, lacerate, incurved on drying. Hymenium poroid. Pores 4-5 per mm, angular, absent along margin, white, pale brown on bruising, tube 1-2 mm long, concolourous with pore surface. Context 1 mm thick, white, homogenous. Odour not distinctive.
Hyphal system monomitic, generative hyphae with clamp-connections, thin to slightly (up to 1 μm) thick-walled, metachromatic in cresyl blue. Pileipellis a regular cutis made of hyphae that are 2-3 μm wide, hyaline, thin- to slightly (up to 1 μm) thick-walled. Pileal trama subparallel, generative hyphae 2-6 μm wide, hyaline, smooth, thin- to slightly (up to 1 μm) thick-walled, with frequent clamp-connections. Hymenial trama subparallel, hyphae 2-5 μm wide, hyaline, smooth, thin- to slightly (up to 1 μm) thick-walled, with frequent clamp-connections. Cystidia absent. Basidia 15-21 × 4-5 μm, clavate, 4-sterigmate, with basal clamp-connections. Basidiospores 5-7 × 2-3 μm, L = 5.8 μm, W = 2.5 μm, Q = 2-3, Qm = 2.37, cylindrical, usually curved at one end, hyaline, often monoguttulate, thin-walled, smooth, inamyloid in Melzer's reagent, acyanophilous in cotton blue.
