[4] Oxyporus was first classified as a section of the genus Coriolus by Hubert Bourdot & Amédée Galzin in 1925.

In the latter case, the crust is typically broadly attached to the substrate and has a fibrous to woody texture.

Pileate fruit bodies are white to deep cream in color, have a velvety texture, and are frequently covered with mosses.

Basidiospores are spherical to broadly ellipsoid, thin- to thick-walled, smooth, hyaline, and have a negative reaction to Melzer's reagent.

[10] This species also produces an antifungal compound, 5-pentyl-2-furaldehyde, that inhibits the mycelial growth of Alternaria alternata, Botrytis cinerea, Colletotrichum gloeosporioides, Fusarium oxysporum f. sp.
