Ciri dan struktur

Basidiome annual, resupinate, membranaceous, effused to approximately ten centimetres in diameter. Mature parts continuous, with a cottony texture when fresh and a rather firm, fibrous and compact, yet quite soft and elastic texture when dried. Hymenium smooth; greenish-brown when fresh, pale brown when dried. Immature parts discontinuous, byssoid with a cottony texture, both when fresh and when dried. Subhymenium and hymenium of the immature parts initially yellowish-white to pale brown, in the dried basidiome, when more mature pale brown. Subiculum well developed, loose, fibrous, pale yellowish-brown to pale orange brown; forms the outer edge of the basidiome, extending noticeably beyond the hymenium. Hyphal cords lacking, but loose bundles of subicular hyphae sometimes present. Hyphal system monomitic, clamp connections and reaction in Melzer’s reagent absent from all hyphae. Subicular hyphae noticeably long and straight, thick-walled; forming a loose tissue. Individual hyphae 3.1–) 3.2–4.3 (–4.8) μm wide, with a mean width of 3.7 μm; pale orange brown to brown in KOH, orange brown in water. Subhymenial hyphae often somewhat sinuous, thin to thick-walled; forming a rather dense tissue. Individual hyphae 3.6–5.7 (–7.1) μm wide, with a mean width of 4.5 μm; pale grey brown to grey brown or brown in KOH; orange brown to pale green in water (but not with the blue green reaction present in other species), with strongly granular contents. Encrustation not seen. Basidia with four slightly curved sterigmata, occasionally two-sterigmate; clavate to narrowly clavate, sometimes clavopedunculate, thin-walled, with one-three slight constrictions.

Habitat dan peran ekologis

The only specimen recorded to date of P. umbrinascens is the type collection, which was obtained in an old, coastal, deciduous forest on soil with high pH. UNITE sequence metadata shows that the species forms ectomycorrhiza with at least Corylus avellana (Kõljalg et al. 2005, Nilsson et al. 2019). Basidiomata encountered in: Sweden. Soil or root tip samples confirm presence also in: Italy.
