Amphinema P. Karst. 1892, in Gorjón, Studies in Fungi 5(1), 156 (2020).

Diagnosis: Basidiome resupinate, pellicular, rarely membranaceous, hymenophore smooth or finely velutine due to the projecting cystidia, margin usually with rhizomorphs. Hyphal system monomitic, hyphae yellowish, more or less thin-walled, loosely interwoven, with clamps at all septa (with simple-septa in Amphinema angustispora), usually encrusted. Cystidia hyphoid (leptocystidia), cylindrical, projecting, with clamped septa, slightly thick-walled, yellowish, covered with small granules. Basidia clavate, with 4-sterigmata, and a basal clamp. Basidiospores ellipsoid (fusiform in Amphinema angustispora), smooth, slightly thick-walled, hyaline, inamyloid, indextrinoid, stained in cotton blue but not truly cyanophilous.
