Lyoathelia laxa (Burt) Hjortstam & Ryvarden 2004, in Hjortstam & Ryvarden, Synopsis Fungorum, 18, 8-13 (2004).

Diagnosis: Basidiome resupinate, loosely adnate, effused, pellicular, 50–100 μm thick, fragile, hymenophore smooth, white to pale yellowish white, margin white, thinning out, fibrillose or fimbriate, sometimes with mycelial cords.

Hyphal system monomitic; subiculum whitish, with thin-walled and narrow hyphae, 1.5–3 μm wide, smooth or slightly encrusted, subhymenial hyphae short-celled, up to 5 μm wide, all hyphae with clamp connections.

Cystidia distinctly capitate, sometimes with an adventitious septum, thin-walled, 35–60 x 5.5–7 μm, sparsely encrusted, projecting as much as 40 μm beyond the hymenial surface.

Basidia pedunculate, often with one or two oil drops in the protoplasm, thin-walled, 18–25(–30) x 7–9 μm, with four sterigmata and a basal clamp connection.

Basidiospores almost globose, thin- to moderately thick-walled, smooth, with a distinct apiculus, 6–8 x 5.5-6.5(–7) μm, inamyloid, indextrinoid and acyanophilous.
