Etymology.

musicola (Lat.), refers to the growth on the mosses, which is located Bryophyta.

Basidiomata.

Annual, resupinate, adnate, very difficult to separate from substrate, without odor or taste when fresh, up to 7 cm long, 2 cm wide, and 150 µm thick. Hymenial surface arachnoid, white when fresh and becoming white to cream when drying. Sterile margin narrow, slightly cream, up to 1 mm wide. The basidiomata grow on the surface of muscus.

Hyphal system.

Monomitic, generative hyphae with clamp connections, colorless, thin to slightly thick-walled, rarely branched, interwoven, 2.5–4.0 µm in diam, IKI –, CB –; tissues unchanged in KOH.

Hymenium.

Cystidia capitate, thin-walled, smooth, slightly constricted at the neck, with a globose tip, 12.5–20.0 × 3.5–5.0 µm; cystidioles absent. Basidia clavate, colorless, thin-walled, with four sterigmata, 11.0–15.5 × 3.5–5.0 µm; basidioles in shape similar to basidia, but slightly smaller.

Basidiospores.

Broadly ellipsoid to globe, colorless, thin-walled, smooth, with one guttate, IKI –, CB –, 4.0–5.5 (– 6.0) × 3.5–5.0 (– 5.5) µm, L = 4.77 µm, W = 4.35 µm, Q = 1.07–1.13 (n = 60 / 2).
