Classification: Amerosporae, Fossil Fungi

Van der Hammen (1954a) instituted the genus Diporisporites from the Maastrichtian (72–66 mya) sediments of Eastern Cordilleras, Colombia, with the following short diagnosis: Fungal spores “with two small pores” (vide Jansonius & Hills 1976, card 810). Elsik (1968) provided an elaborate, emended generic diagnosis to include unicellate, diporate fungal spores with one pore on each opposite end of the spore. Pores may be modified, i.e., with atrium, annulus, or septum forming a pore chamber—shape and ornamentation variable.

Type species: Diporisporites elongatus Hammen 1954a (designated by van der Hammen 1954b).
