Fruiting body 2-8 cm broad, fan-shaped, convex with an incurved margin, becoming nearly plane, the margin then often wavy; surface hygrophanous, moist, densely tomentose, pale apricot-brown to buff-brown, lighter in age; flesh thin, pliant to tough, buff-brown, unchanging; odor skunk-like; taste unpleasant; stipe and veil absent.
Gills radiating from a sessile attachment point, close, relatively narrow, pale orange-buff, darkening slightly in age.
Spores 4.5-6.5 x 2-2.5 µm, bean-shaped, smooth, inamyloid; spore print pale salmon-pink.
Clustered or forming overlapping shelves on log and branches of hardwoods and conifers; fruiting from mid to late winter.
Unknown and unlikely to change due to a tough context and fetid odor.
This fleshy shelf fungus looks like and was once placed in Pleurotus, but was moved into its own genus because of spore and context differences. The skunk-like odor and pale orange, tomentose cap easily distinguish it from any of our local Panus or Crepidotus species.
