Mycothele

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

            Diagnosis: Basidiome resupinate to disciform, solitary or in small groups of 3-5, attached by a small central base, membranaceous to coriaceous. Hymenial surface hydnoid with sterile aculei of tramal origin (fascicles arising from the basal layer, traversing the context and projecting to 130 μm, 20-30 per mm, apices long-acuminate, of cemented hyphae embedding masses of crystals often placed obliquely). Hyphal system monomitic, hyphae hyaline, with clamps, with large masses of crystals in the trama of the aculei. Cystidia and gloeocystidia absent. Basidia stalked clavate, hyaline, with 4-sterigmata and a basal clamp. Basidiospores broadly ellipsoid to subglobose, smooth, hyaline, thin-walled, inamyloid, dextrinoid, CB–.

            Monotypic genus, only found on Rhopaloslylis sapida, an endemic species of Palmae in New Zealand. Characterized by the small basidiomes and peculiar fascicles. Basidiomes may be disciform and range in diameter from one to a few mm. The surface is pallid sulphur-yellow and densely velutinate with projecting fascicles, in this feature simulating some delicate Hydnum (Jülich 1976).
