Peniophora pseudoversicolor

On decaying dead wood on the ground, preferentially on small branches of oak or holm oak (Quercus), with orange basidiomata, smooth to slightly rugose surface, very thin, with a whitish growth margin.

Hyphal system monomitic; hyphae cylindrical, smooth, hyaline, thin-walled, 3 to 5 µm wide, septate with clamp connections.

Lamprocystidia (metuloids) abundant, very thick-walled, 35 to 50 µm long, 7 to 9 µm wide, heavily encrusted with crystals over their surface.

Gloeocystidia scattered, deeply embedded in the hymenium, cylindrical to fusiform with a pointed tip, 30 to 90 µm long, 9 to 14 µm wide, with contents darkening noticeably in sulfovanillin.

Basidia cylindrical to slightly clavate, sinuous, 30 to 45 µm long, 4.5 to 6 µm wide, clamped at the base, 4-spored.

Spores cylindrical-ellipsoidal to slightly allantoid, smooth, hyaline, thin-walled, 6.5 to 9 µm long, 3.5 to 4.5 µm wide, with a lateral apiculus at one end, inamyloid in Melzer's reagent.
