Heteroacanthella

Heteroacanthella Oberw. 1990, in Gorjón, Studies in Fungi 5(1), 216 (2020).

            Diagnosis: Basidiome effused, dense, ceraceous, grey, with a distinct margin. Hyphal system monomitic, with clamp connexions in the type species (simple-septate in H. variabilis). Hymenium thin, densely agglutinated, composed of one or more layers of basidia and hyphidia arising from laterally branching subicular hyphae. Hyphidia variously cylindrical, clavate, or irregularly swollen, acanthoid, with numerous simple or branched apical processes. Basidia subglobose to pyriform or ellipsoid, acanthoid, with numerous simple processes up to 2 μm long scattered around the apex, with one long sterigmata in the type species (one or usually two sterigmata in H. variabilis), occasionally producing a single, short, subsidiary sterigma and thus appearing furcate. Basidiospores globose to subglobose, smooth, hyaline, inamyloid, some producing secondary spores by replication.
