The genus Boidinella is erected to accommodate Sistotremella cystidiolophora and Dendrothele globulispora. The genus is characterized by effuse, soft, farinaceous to membranous basidiomata, delicate dendrohyphidia, obclavate leptocystidia, urniform basidia with 4 sterigmata, and subglobose to ellipsoid basidiospores with hyaline, slightly thickened, smooth, cyanophilous walls. Boidinella is compared with Dendrothele, Hypochnicium, Sistotremella, and Leptocorticium.
