Type species: Cocconia placenta (Berk. & Broome) Sacc., Syll. fung. (Abellini) 8: 738 (1889).

Rhytisma placenta Berk. & Broome, J. Linn. Soc., Bot. 14(no. 74): 131 (1873) [1875].

Notes: Jayasiri et al. (2016) re-examined the holotype and confirmed its family level placement within Parmulariaceae. The genus was reported as pathogenic on living leaves of Symplocos spicata (see morphology in Inácio and Cannon 2008; Jayasiri et al. 2016; Wijayawardene et al. 2018, 2020). Cocconia is characterized by superficial, shield-like, dark brown to black, carbonaceous, flated ascostromata producing thick-walled, cylindrical asci and ellipsoidal,1-septate, brown ascospores (Jayasiri et al. 2016).
