Description:
Basidiocarp effused to effuse-reflexed, attached on the substrate, in patches about a few centimetres across, up to 1 mm thick. Hymenium surface papillate or shallowly tuberculate, becoming crustose to corneous when dry, reddish brown to dark purplish brown. Superior surface cottony, fluffy, membranous, light pink to rose, with reddish aqueous droplets secreted from pores in autumn; compact, woolly, partly powdered, pinkish purple to purplish brown. Hyphal system monomitic, generative hyphae with clamp connections. Subicular generative hyphae 3 µm wide, with thick solid walls, yellowish brown, sometimes with multiple clamp connections on the single septum. Basidiospores infrequent, ellipsoid to narrowly ellipsoid, smooth, thin-walled, hyaline. Basidia not observed. Conidia prevalent, abundant, in branched chains, subglobose to ellipsoid, sometimes irregular, 5–6×4 µm, with thick walls, pale brownish, with lipid bodies inside, chipping off from each one and showing the remains of the linking walls at both ends, sometimes shed with segments of supporting hyphae.
