Skeletocutis cummata

Ciri dan struktur

Basidiocarps annual; half-resupinate to pileate; up to 3 cm wide and (pilei) up to 1 cm 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 to cream coloured when young, turning ochraceous with almost orange hues; pore surface 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; pores (5–)7–8(–13) per mm. Hyphal structure: the outer layer of context typically with a loose, fibrous texture composed of radially orientated encrusted hyphae (tomentum). Skeletal hyphae in context / subiculum (1.0–)2.0–3.5(–5.0) µm wide, in trama 2.0–4.0(–5.0) µm wide, generative hyphae in trama 1.0–2.0(–2.6) µm wide. Basidiospores (2.8–)2.9–3.4(–3.9)×0.5–0.8(–0.9) µm, L=3.1 µm, W=0.66 µm, Q’=(3.3–)3.8–6.0(–6.6), Q=4.68, n=270/9.

Habitat dan peran ekologis

Boreal, Eurasian taiga; known from Fennoscandia, Czech Republic and Far East. The species seems to be rather rare in Europe but possibly more common in the Far East where Spirin (H) has collected it abundantly. The species has been found growing on fallen spruce logs (Picea abies, P. jezoënsis) but also on Abies nephrolepis and Larix sp.
