Habitat and ecology: — Climate of the sample collection site is monsoon humid, and the forest type is evergreen broad-leaved forest, and the samples were collected on an angiosperm stump.
description
Fruiting body: — Basidiomata annual, resupinate, soft to juicy when fresh, without odor or taste, bone hard when dry, up to 3 cm long, 2.5 cm wide and 0.5 mm thick at centre. Pore surface olivaceous when fresh, olivaceous to black when dry, slightly staining when touched or bruised; sterile margin narrow, up to 1 mm wide; pores round, shallow, 2 – 3 per mm; dissepiments thin, entire. Subiculum very thin to almost lacking, olivaceous to brown, hard corky. Tubes concolourous with the pore surface, bone hard, up to 0.4 mm long. Hyphal structure: — Hyphal system monomitic; generative hyphae with simple septa, IKI-, CB +; tissues unchanged in KOH. Subiculum: — Subicular generative hyphae colorless, thin to slightly thick-walled, occasionally branched, more or less straight, regularly arranged, 4 – 6 µm in diam. Hymenium: — Tramal generative hyphae colorless, thin to slightly thick-walled, moderately branched, interwoven, 3.5 – 5.5 µm in diam; cystidia larger, strongly encrusted, colorless, thin-walled, 30 – 76 × 5 – 8.5 µm; basidia mostly short clavate to barrel-shaped, thin-walled, smooth, with four sterigmata and a simple basal septum, 8 – 11.5 × 5.5 – 7 µm (x ̅ = 9.8 × 6.3 µm); basidioles in shape similar to basidia, but smaller. Basidiospores: — Subglobose, colorless, thin-walled, smooth, bearing a larger guttule, IKI-, CB-, 4 – 5.5 × 3.5 – 5 µm, L = 4.5 µm, W = 4 µm, Q = 1.04 – 1.08 (n = 60 / 2).
etymology
