Index Fungorum number: IF 821453; Facesoffungi number: FoF 08185, 1 morphological species (Species Fungorum 2021), 1 species with molecular data.

           Saprobic or pathogenic on branch. Sexual morph: Unknown. Asexual morph: Conidiomata pycnidial, pale brown to brown, solitary or confluent, superficial or semi-immersed, pycnidial wall of textura angularis, 2–4 layered, glabrous or ornamented, subglobose to ovoid, ostiolate. Conidiophores if present, septate, hyaline, straight or sinuous to slightly curved, slightly tapering towards the apex. Conidiogenous cells integrated in the conidiophore, phialidic, hyaline, smooth-walled, ampulliform when terminal, with a more or less cylindrical collarette, several per conidiophore. Conidia aseptate, hyaline, smooth- and thin-walled, ellipsoidal to cylindrical, guttulate (Adapted from Valenzuela-Lopez et al. 2017).


          Type species: Paracucurbitaria corni (Bat. & A.F. Vital) Valenz.-Lopez, Stchigel, Guarro & J.F. Cano


Notes: Paracucurbitaria was introduced by Valenzuela-Lopez et al. (2017) with P. corni as type species. Paracucurbitaria is characterized by pycnidial conidiomata straight or sinuous to slightly curved conidiophores, phialidic hyaline conidiogenous cells with hyaline ellipsoidal to cylindrical conidia. Phylogenetically, Paracucurbitaria is a distinct and well-supported monophyletic lineage in Cucurbitariaceae.
