Boidinia

Boidinia Stalpers & Hjortstam 1982, in Gorjón, Studies in Fungi 5(1), 170 (2020).

Diagnosis: Basidiome resupinate, effuse, thin, soft, fragile, smooth, densely farinaceous to membranous, margin more or less abrupt. Hyphal system monomitic with clamped hyphae. Dendrohyphidia delicate. Leptocystidia obclavate, attenuate, sometimes moniliform. Basidia urniform, oleaginous, walls cyanophilous, 4-sterigmate. Basidiospores subspherical to ellipsoid, walls hyaline, smooth, slightly thick, cyanophilous, not amyloid. On dead stems of monocots.

Index Fungorum Number: IF17162

Type Species: Boidinia furfuracea (Bres.) Stalpers & Hjortstam 1982

Notes: Boidinella is characterized by the effuse, soft, densely farinaceous or membranous basidiomes, urniform basidia with 4 sterigmata, obclavate leptocystidia, dendrohyphidia, and basidiospores with smooth, slightly thickened, cyanophilous walls. Boidinella is morphologically similar to Dendrothele but differing in the delicate and fragile nature of dendrohyphidia, cystidia, and basidia in the former. Boidinella lacks crystals and inhabits dead stems of monocots. Basidiospores in Sistotremella have also cyanophilous walls but are much smaller and basidia always have 6-8 sterigmata. Leptocorticium also shows similarities to Boidinella, but basidiospore walls are thin and not cyanophilous in the former. For further comments see Nakasone (2011).
