Notes –Parapyrenochaetaceaewas 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 withPyrenochaeta. Several isolates previously recognized inPyrenochaeta, are proposed to be in the new familyParapyrenochaetaceae(Valenzuela-Lopez et al. 2018).Pyrenochaetapreviously belonged toCucurbitariaceaeof order Pleosporales which is a family of economic importance including many plant pathogens, endophytes and saprobes with a wide host range.Cucurbitariaceaeis a poorly known family, introduced by Winter (1885). In the last revision ofCucurbitariaceae, four sexual genera (Cucurbitaria,Curreya,RhytidiellaandSyncarpella) and two asexual genera (PyrenochaetaandPyrenochaetopsis) 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 generaphomaandpyrenochaetahas been clarified and better delimitation of members inCucurbitariaceaehas been achieved with the establishment ofParapyrenochaetaceae.
