Radulomycetopsis

Radulomycetopsis Dhingra, Priyanka & J. Kaur, in Dhingra et al., Mycotaxon 119: 133 (2012)

Etymology: The name of the genus is based on the resemblance with genus Radulomyces

Diagnosis: Basidiocarp resupinate, adnate, effused, membranous-ceraceous; hymenial surface smooth to slightly tuberculate, orange to brownish orange to reddish brown; margins fibrillose, concolorous but paler; hyphal system monomitic; generative hyphae branched at wide angles, without clamps, basal hyphae covered with a thick sheath of brownish red matter, which dissolves in 3% KOH; cystidia projecting, thin- to slightly thick-walled; simple to somewhat branched hyphoid structures present in the hymenium; basidia clavate to subclavate, 4-sterigmate, without a basal clamp; basidiospores broadly ellipsoid to subglobose, smooth, thin- to slightly thick-walled, inamyloid, acyanophilous; both basidia and basidiospores rich in oil drops.

Index Fungorum number: IF560517

Type species: Radulomycetopsis cystidiata Dhingra, Priyanka & J. Kaur, in Dhingra et al., Mycotaxon 119: 133 (2012)

Notes: Radulomycetopsis resembles Radulomyces in producing simple to somewhat branched hyphoid structures in the hymenium, similar basidia, and broadly ellipsoid to subglobose basidiospores that are thin- to slightly thick-walled, non-amyloid, acyanophilous, and with oil rich protoplasm. Radulomycetopsis differs in having dark colored fruitbodies, hyphae without clamps, and presence of cystidia, a combination of features that supports an independent genus.
