Auriscalpium

Auriscalpium Gray 1821, in Gorjón, Studies in Fungi 5(1), 167 (2020).

Diagnosis: Basidiome stipitate and pileate, hymenophore hydnoid, upper sterile surface hirsute. Hyphal system dimitic, generative hyphae with clamps, skeletal hyphae present in the context. Gloeocystidia present. Basidia subclavate, with 4-sterigmata, and a basal clamp. Basidiospores ellipsoid, ornamented, amyloid.

Index Fungorum Number: IF17139

Type Species: Auriscalpium vulgare Gray 1821

Notes: Auriscalpium is a stipitate hydnoid genus, although it does not share the corticioid habit we include it in this manual to highlight the variability of the basidiome structure present within the russuloid lineage. It is phylogenetically very closely related to Gloiodon, with effuse-reflexed basidiome and to Dentipratulum, with hydnoid gregarious basidiomes (Larsson & Larsson 2003, Larsson 2007).
