Umbellus Xue W. Wang & L.W. Zhou 2023, in Wang, & Zhou, Journal of Fungi, 10(1), 22 (2023).
Etymology: Umbellus (Lat.), referring to the large umbrella-shaped crystalline head of cystidia.
Diagnosis: Distinguished by capitate cystidia with a large umbrella-shaped crystalline head. Basidiomes annual, adnate and resupinate. Hymenophore smooth to grandinioid or odontioid to hydnoid, white to cream; margin thinning out, arachnoid, concolorous or paler than subiculum. Hyphal system monomitic; generative hyphae with clamp connections. Cystidia dimorphic: (1) arising from subhymenium and more or less enclosed in the hymenium or strongly projecting for the greater part of their length, cylindrical, unevenly thick-walled with a narrow or wide lumen, rooted at the base, gradually tapering, broadly rounded at the apex and covered by a large umbrella-shaped crystalline head; (2) originating laterally on subicular hyphae with the same morphology as those arising from subhymenium but smaller in size and stalk slightly thick-walled. Basidia subclavate to clavate-cylindrical, barrel-shaped or suburniform, with a basal clamp connection and four sterigmata. Basidiospores oblong-ellipsoid or broadly ellipsoid, hyaline, smooth, thin-walled, indextrinoid, inamyloid, acyanophilous.
