Cystocoleus was introduced by Thwaites (1849) based on C. ebeneus. Subsequently, C. niger and C. rupestris were described by Rabenhorst (1870) and Hariot (1890). However, Hawksworth et al. (2011) synonymized C. nigra under C. ebeneus and transferred C. rupestris to Racodium. Currently, Cystocoleus is a monotypic genus containing C. ebeneus.

Type species: Cystocoleus ebeneus (Dillwyn) Thwaites.

Other accepted species: Species Fungorum – search Cystocoleus.
