Basidiome cartilaginous, ceraceous when fresh. Hymenial surface warted, ochraceous; margin white. Subhymenial hyphae thin- to somewhat thick-walled, 2-3.5 µm wide, densely interwoven, sometimes fasciculate, not gelatinised. Clamps absent (or very rare on subicular hyphae). Tramal cystidia hyaline, clavate to cylindrical, thin- to generally somewhat thick-walled except at the apex, smooth or more rarely loosely encrusted with crystalline material, sometimes with a secondary septum, immersed or projecting up to 12 µm. Basidia typically narrowly clavate to cylindrical, 15-23 x2.5-4 µm, but in the youngest parts narrowly cylindrical, 20-32 X 2.5-3.5 µm Spores hyaline, thin-walled, ellipsoid, 3.7-5.5 x 2-2.5 x 2.5-3.3 µm, smooth, not amyloid.

The fungus on the type specimen covers both the bark of Corynocarpus laevigatus and the stroma of a pyrenomycete. It causes a weak white rot. The species fits well in Phlebiopsis Jülich because of the densely interwoven subhymenial hyphae, the narrow Basidia, and the shape of the cystidia; the fact that the cystidia are mostly encrusted in other species of the genus is not considered important at the generic level.
