Membranomyces

Membranomyces Jülich 1975, in Gorjón, Studies in Fungi 5(1), 239 (2020).

            Diagnosis: Basidiome resupinate, effused, subceraceous to membranaceous, hymenophore smooth. Hyphal system monomitic, hyphae simple-septate, thin- to slightly thick-walled. Cystidia and gloeocystidia absent, hyphoid cystidiols may be present. Basidia clavate, 2-4-spored, simple-septate at the base, guttulate. Basidiospores ellipsoid to subglobose, smooth, thin- or slightly thick-walled, inamyloid, indextrinoid, distinctly guttulate.

            Membranomyces is characterized by the simple-septate generative hyphae, absence of cystidial elements, and large ellipsoid to subglobose basidiospores. It mainly differs from Clavulicium in the absence of clamps and gloeocystidia. Membranomyces is considered as the sister group of Clavulina cristata which provides another example of a resupinate-clavarioid transformation (Larsson et al. 2004).
