Classification: Fossil Ascomycota, Fungi

Kar et al. (2010) instituted Dictyomykus from the Bhuban Formation (Early Miocene, 23–16 mya) in Tlangsam, Mizoram, India. This genus is characterized by small conidiophores, closely placed to form a sporodochium like cluster. The conidia are elliptical, basal part narrowed than terminal, exhibit 4–8 branches, parallel, develop from a basal cell, laterally fused, multiseptate, septa margin not constricted, and incurved at the tip. The spore wall is laevigate (Kar et al. 2010). Only one species listed in Index Fungorum (2023) under this genus.

Type species: Dictyomykus ellipticus R. Kar, Mand. & R.K. Kar.
