NotesParapyrenochaetaceae was introduced by Valenzuela-Lopez (2018) after a detailed morphological comparison followed by molecular analysis. The name of the family was derived from its close relationship with Pyrenochaeta. Several isolates previously recognized in Pyrenochaeta, are proposed to be in the new family Parapyrenochaetaceae (Valenzuela-Lopez et al. 2018). Pyrenochaeta previously belonged to Cucurbitariaceae of order Pleosporales which is a family of economic importance including many plant pathogens, endophytes and saprobes with a wide host range. Cucurbitariaceae is a poorly known family, introduced by Winter (1885). In the last revision of Cucurbitariaceae, four sexual genera (Cucurbitaria, Curreya, Rhytidiella and Syncarpella) and two asexual genera (Pyrenochaeta and Pyrenochaetopsis) were accepted (Doilom et al. 2013). The latter two genera are characterised by phoma-like, setose pycnidia, and hyaline, aseptate conidia (De Gruyter et al. 2010, 2013). Generic concept of the genera phoma and pyrenochaeta has been clarified and better delimitation of members in Cucurbitariaceae has been achieved with the establishment of Parapyrenochaetaceae.
