On decaying wood on the ground, with completely resupinate fructifications, very thin, greyish-white, closely adnate to the substrate, with a diffuse, very irregular, whitish growing margin.

Monomitic hyphal system, with hyaline generative hyphae, thin- to moderately thick-walled, 2 to 4 µm wide, branched, occasionally with encrustations on their surface, septate and clamped.

Cystidia subulate, thick-walled, 60 to 85 µm long, 4 to 6 µm wide at the base, with their surface covered with crystals, with a pointed, hyaline, thin-walled apex.

Basidia suburniform, 15 to 18 µm long, 4 to 6 µm wide, with basal clamps, 4-spored.

Spores cylindrical, sinuous to vermiform (worm-like), smooth, hyaline, thin-walled, 18.5 to 24 µm long, 2 to 2.5 µm wide, with a slightly more pointed end where the apiculus is located, and with oil droplets of various sizes inside.
