Aphanobasidium is a genus of corticioid or crust fungi in the Radulomycetaceae family. The genus has a widespread distribution and contains several species.{{cite book |vauthors=Kirk PM, Cannon PF, Minter DW, Stalpers JA |title=Dictionary of the Fungi |edition=10th |publisher=CABI |location=Wallingford |year=2008|page=41|isbn=978-0-85199-826-8}} 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. Griffith.{{Cite journal |last1=Leal-Dutra |first1=Caio A. |last2=Griffith |first2=Gareth W. |last3=Neves |first3=Maria Alice |last4=McLaughlin |first4=David J. |last5=McLaughlin |first5=Esther G. |last6=Clasen |first6=Lina A. |last7=Dentinger |first7=Bryn T.
