Type species: Cyclostomella disciformis Pat., Bull. Herb. Boissier 4: 656 (1896).
Notes: Cyclostomella comprises four species (Inácio and Cannon 2008). The genus was reported as pathogenic on living leaves, usually in tropical regions such as Costa Rica, Cuba and Brazil. A comparison of morphological features of four taxa of Cyclostomella was provided by Inácio and Cannon (2008). Cyclostomella is characterized by superficial, circular to elliptical, disc-like, black, rather flat ascostromata producing cylindric to clavate to subglobose asci and ellipsoid, dark brown, 1-septate ascospores (Inácio and Cannon 2008).
