Mycostigma

Mycostigma Jülich 1976, in Gorjón, Studies in Fungi 5(1), 243 (2020).

            Diagnosis: Basidiome consisting of minute globules, separated or aggregated but never confluent, connected by a few hyaline hyphae. Hyphal system monomitic, hyphae indistinct, probably with clamps, hyaline, cylindrical or somewhat torulose, thin-walled. Cystidia or gloeocystidia lacking. Basidia hyaline, clavate, thin-walled, rather small, probably clamped, 4-spored. Basidiospores ellipsoid, thin-walled, smooth, hyaline, inamyloid, CB–.

            Mycostigma, a monotypic genus, is typified by Corticium aegeritoides, a species characterized by the gregarious basidiome formed by minute globules up to 0.1 mm in diam., the lack of cystidial elements and the absence of any reaction in Melzer's reagent or cotton blue (Jülich 1976). The phylogenetic relationships of Mycostigma are still unclear.
