Aphanobasidium is a genus of corticioid or crust fungi in the Radulomycetaceae family.

The genus has a widespread distribution and contains several species.

[1] This genus was formally considered to be part of the Pterulaceae family.

A major reclassification of the Pterulaceae family occurred in 2020 and the genera Aphanobasidium, Radulomyces and Radulotubus were moved to a new family, Radulomycetaceae by the mycologists Caio A. Leal-Dutra, Bryn Tjader Mason Dentinger and Gareth W.
