Basidiome resupinate, hymenial surface smooth, pale brown to buff, margin indeterminate. Hyphal system monomitic, hyphae thin to usually thick-walled, hyaline to yellowish, with clamps. Hymenium a palisade of basidia and lamprocystidia. Gloeocystidia absent. Lamprocystidia conical, hyaline to yellowish, distinctly thick-walled, walls up to 2–3 µm thick, encrusted with large irregular crystals, encrusted part up to 40 × 10–20 µm, with a basal clamp. Basidia cylindrical to clavate, 12–15 × 3–5 µm, hyaline, with four sterigmata, and a basal clamp. Basidiospores narrowly ellipsoid to cylindrical, (3.5–)4–5 × 2–2.5 µm, smooth, thin-walled, IKI– ( Fig. 12 View FIGURE 9–12 , 22 View FIGURE 17–22 ).

The species is characterized by a pale brown basidiome, hyphae with clamps, large encrusted cystidia, absence of gloeocystidia, and small basidiospores. It is morphologically related to Peniophora exima H.S. Jacks. and Peniophora pithya (Pers.) J. Erikss. in the Peniophora molesta -group (cf. Andreasen & Hallenberg 2009) but this species group differ in the presence of gloeocystidia and slightly larger basidiospores.
