Remarks (internal):Gloiodon is undoubtedly closely related to Auriscalpium S. F. Gray. Both genera include species with a hydnoid hymenophore, gloeoplerous hyphae, and amyloid, ornamented basidiospores. How-ever, while species of Gloiodon have pileate-sessile or effusedreflexed basidiomes, those of Auriscalpium are characterized by stipitate basidiomes. Maas Geesteranus (1963, 1971) included both genera in the Auriscalpiaceae Maas Geest. Later, Donk (1964) transferred Lentinellus P. Karst. to the family because of the micro-morphological similarities of Lentinellus, Gloiodon and Auriscalpium, even though Lentinellus is comprised of lamellate species. Stalpers (1996) included Auriscalpiaceae and five other families in the Hericiales and provided short descriptions of the families to which the reader is referred for further details. Based on recent DNA investigations, Hibbett & Thorn (2001) have accepted Auriscalpium, Gloiodon and Lentinellus and included Gloeodontia Boidin in the Auriscalpiaceae, and their data indicate that the Auriscalpiaceae belongs to the Russuloid clade.
