Classification: Amerosporae, Fossil Fungi.

The monotypic fossil genus Basidiosporites was instituted by Elsik (1968) from the Rockdale lignite (Palaeocene, 66–56 mya) from a locality 11 km southwest of Rockdale, Milam County, Texas, USA (Salard-Cheboldaeff & Locquin 1980). Basidiosporites is characterized by oval to capsular, monoporate, unicellate, and psilate fungal spores with the pore offset from one apex. No basal attachment area is evident. Shape variables generally elongate in some fashion (Saxena & Tripathi 2011). There are four species included in Index Fungorum (2023) under this genus.

Type species: Basidiosporites fournieri Elsik.
