MycoBank number: MB 1068; Index Fungorum number: IF 1068; Facesoffungi number: FoF 08113; 1 morphological species (Species Fungorum 2020), molecular data unavailable.

Type species: Cirsosiopsis violacescens Butin & Speer, Sydowia 31(1–6): 10 (1979) [1978].

Notes: The monotypic genus was introduced by Butin and Speer (1978) with its family placement in Microthyriaceae. Wu et al. (2014) re-examined the holotype of type species C. violacescens and transferred it to Parmulariaceae based on its morphological similarity with Parmularia. This genus is characterized by black and discoid ascostromata opening by irregular disintegration at the centre, globose to subglobose asci and 1-septate, ellipsoid to ovate ascospores (Wu et al. 2014).
