Remarks (internal):The hygrophanous basidioma with smooth to tuberculate hymenial surface is an important character to recognize R. confluens in the field. Microscopically, the sinuous clavate basidia with oily contents and ellipsoid to subglobose slightly thick-walled basidiospores with oily contents are diagnostic characteristics.

Description:Radulomyces confluens (Fries: Fries) M. Christiansen, Dansk Bot. Ark. 19: 230, 1960. (Fig. 68) Thelephora confluens Fr., Obs. Mycol. 1: 152, 1815.

Distribution: Africa, Asia [China (Tai, 1979), Iran (Hallenberg, 1981b), Japan (Ito, 1929b)], Australasia, Europe, and North and South America.
Basidiomata resupinate, adnate, at first orbicular and then becoming confluent, hygro­phanous when wet, 50-400 µm thick; hymenial surface pale gray, "Smoke Grey", "Buff' to "Ochreous", smooth to tuberculate; margin concolorous with the hymenial surface, thin­ning out, indeterminate, sometimes fimbriate under the lens (x 20). In vertical section, subhyaline, membranous to ceraceous, with a basal layer composed of horizontally parallel hyphae. Hyphal system monomitic; generative hyphae 1.5-4.5 µm in diam, smooth, thin-walled, nodose-septate; cystidia lacking, but hyphidia present in the hymenium; basidia clavate, sinuous, 35-60 x 7-9.5 µm, with a basal clamp and oily contents, producing 4 sterigmata; basidiospores ellipsoid to subglobose, 7-12x6-8.5 µm, smooth, slightly thick-walled (ca. 0.5 µm), with oily contents, non-amyloid, pale cream to "Buff" in spore print.
