Skeletocutis ochroalba

Ciri dan struktur

Basidiocarps annual or possibly perennial; half-resupinate to pileate; up to 3 cm wide and (pilei) up to 8 mm thick; hard when dry but easy to break apart; pilei nodulous or thick but steeply sloping, protruding up to 1 cm; margin of pileus curved downwards, blunt, with narrow, woolly, ridge on the underside; upper surface matted to minutely pubescent, white or cream coloured when young, turning ochraceous brown; pore surface cream coloured with ochraceous or sometimes salmon/peach coloured tints, sometimes a greenish-grey tint is visible in the tubes; context and subiculum finally coriaceous but looser and fibrous near cap edge and surface; context faintly zonate in longitudinal section with thin dark lines separating layers of growth; tube layer up to 1 mm thick, sometimes divided by a thin white layer where tubes are filled with arbuscule-like ‘binding hyphae’, otherwise pale buff; pores (6–)7–8(–10) per mm. Hyphal structure: the outer layer of context typically has a loose, fibrous texture composed of radially orientated hyphae. Skeletal hyphae in context / subiculum (1.0–)2.0–3.5(–4.0) µm wide, in trama 2.0–4.6(–6.2) µm wide, generative hyphae in trama 1.0–2.2(–2.9) µm wide. Basidiospores (2.8–)2.9–3.7(–4.0)×0.5–0.8 µm, L=3.1 µm, W=0.67 µm, Q’=3.8–6.0(–7.0), Q=4.65, n=70/3.
