Summary:
Features include 1) resupinate growth on wood, 2) a buff surface with short teeth, 3) amyloid spiny spores, 4) gloeocystidia and encrusted cystidia, and 5) a dimitic hyphal system, the generative hyphae with clamp connections.

Microscopic:
SPORES 4.5-5.5 x 3-4 microns, oval to elliptic, colorless, amyloid and distinctly echinulate in Melzer''s reagent; BASIDIA 4-spored, 20-30 x 4-5 microns, narrowly clavate, with basal clamp connection; CYSTIDIA clustered at tips of teeth, 60-80 x 4-8 microns, cylindric, tapering slightly at the tip, thick-walled, heavily encrusted on upper part, gloeocystidia numerous, 25-40 x 4-6 microns, projecting slightly, fusoid to cylindric, often mammillate, "with highly refractive contents, positive in sulfuric benzaldehyde", with a basal clamp connection; HYPHAE dimitic, generative hyphae 2-3.5 microns wide, thin-walled, with clamp connections, skeletal hyphae 1.5-3 microns wide, thick-walled, aseptate, rarely branched, (Lindsey)
