Type species: Didymellopsis latitans (Nyl.) Sacc. ex Clem. & Shear, Gen. fung., Edn 2 (Minneapolis): 265 (1931).

‚Č° Obryzum latitans Nyl., Flora, Regensburg 68: 298 (1885).

Notes: All species in Didymellopsis are found on lichens with cyanobacterial photobionts, but D. perigena which grows on Catapyrenium squamulosum might be associated with cyanobacteria surrounding the host thallus. Differences between Didymyellopsis and Zwackhiomyces are subtle (Zhurbenko et al. 2015) and a thorough revision of the group, including DNA sequence analyses should be carried out.
