Cyphobasidium

Cyphobasidium Millanes, Diederich & Wedin 2016, in Millanes, et al., Fungal Biology, 120, 1468-1477 (2016)

Etymology: From Latin cyphus (= bowl, cup), in reference to the probasidium, a thick-walled cup-like structure from which the meiosporangium arises.

Diagnosis: Basidiomata inducing conspicuous galls on the host lichen thalli. Galls convex, with a constricted base, often becoming irregular in form. Context hyphae with or without clamps; haustorial branches unknown. Basidia, when mature, consisting of a thick-walled, ellipsoid to elongate lower part (the probasidium) and a thin-walled, cylindrical, often bent, transversely 3-septate, upper part (the meiosporangium); epibasidia short, more or less perpendicular to the basidium. Basidiospores ellipsoid to broadly fusiform, sometimes slightly curved, with a distinct refractive apiculus at the lower end and a rounded upper end. Asexual stage unknown.
