Neopyrenochaeta Valenz.-Lopez, Crous, Stchigel, Guarro & Cano, Stud. Mycol. 90: 54 (2017).
Saprobic or pathogenic on host. Asexual morph: Conidiomata pycnidial, pale brown to brown, solitary, pycnidial wall of textura angularis, setose, ovoid to globose, ostiolate. Conidiogenous cells phialidic, ampulliform or lageniform. Conidia aseptate, hyaline, smooth- and thin-walled, ovoid to subcylindrical. Sexual morph: Unknown (Adapted from Valenzuela-Lopez et al., 2017).
Type species: Neopyrenochaeta acicola (Moug. & Lév.) Valenz. -Lopez, Crous, Stchigel, Guarro & J.F. Cano
Notes: Neopyrenochaeta was introduced by Valenzuela-Lopez et al. (2017) with N. acicula as type species. Neopyrenochaeta is characterized by pycnidial, pale brown to brown, solitary conidiomata, phialidic, ampulliform or lageniform conidiogenous cells and aseptate, hyaline, smooth- and thin-walled, ovoid to subcylindrical conidia. Neopyrenochaeta morphologically resembles Pyrenochaeta but is phylogenetically distant from the type species of Pyrenochaeta, P. nobilis. Neopyrenochaeta acicola, previously known as Pyrenochaeta acicola was not congeneric with the type of Pyrenochaeta. de Gruyter et al. (2010) neotypified Pyrenochaeta acicola and accommodated the genus in Cucurbitariaceae based on phylogenetic analysis of LSU and SSU sequence data. Valenzuela-Lopez et al. (2017) introduced Neopyrenochaetaceae to accommodate Neopyrenochaeta based on phylogenetic analysis of LSU, ITS, tub2 and rpb2 sequences. Neopyrenochaeta is a distinct and well-defined genus in Neopyrenochaetaceae. Molecular markers available for Neopyrenochaeta include LSU, SSU, ITS, TEF1, RPB2 and tub2.
