Type species: Placostromella macrospora Petr., Sydowia 1(1–3): 9 (1947).

Notes: Placostromella was intoduced by Petrak (1947d) with Placostromella macrospora as type species. Later P. amazonensis and P. castanopsis were transferred to Placostromella (Inácio et al. 2005). Three taxa including the type are accepted in Placostromella (morphology see Thambugala et al. 2014b; Wijayawardene et al. 2018, 2020). This genus is characterized by subcuticular, carbonaceous, black, rounded or broadly ellipsoid ascostromata with a single locule, cylindrical to clavate asci and cylindric-ellipsoidal or oblong to obovate ascospores (Thambugala et al. 2014b).
