Neopyrenochaeta Valenz.-Lopez, Crous, Stchigel, Guarro & Cano, in Valenzuela-Lopez et al., Stud. Mycol. 90: 54 (2017)

Facesoffungi number: FoF 07389

Dothideomycetes, Pleosporomycetidae, Pleosporales, Neopyrenochaetaceae

 

Saprobic on the host plant or on submerged stems in freshwater habit, on screen of a mobile phone or from air, or soil (Boerema et al. 2004, Marincowitz et al. 2008, Crous et al. 2015c) Sexual morph: undetermined. Asexual morph Conidiomata brown, pycnidial, solitary, semi-immersed to superficial, globose to subglobose, unilocular, setose, ostiolate. Ostiole circular, papillate or non-papillate, centrally or laterally located. Setae conspicuous or inconspicuous, pale brown to black at the base, paler towards apex, unbranched, septate. Conidiomatal wall composed of thick-walled, brown to hyaline cells of textura angularis to textura prismatica. Conidiophores reduced to conidiogenous cells. Conidiogenous cells formed in the inner cavity of conidiomata, hyaline, enteroblastic, annellidic or phialidic, doliiform to ampulliform or lageniform, determinate or indeterminate, smooth-walled. Conidia hyaline, ovoid to ellipsoidal or subcylindrical, guttulate.

 

Type species: Neopyrenochaeta acicola (Moug. & Lév.) Valenz.-Lopez, Crous, Stchigel, Guarro & Cano, in Valenzuela-Lopez et al., Stud. Mycol. 90: 54 (2017)

 

Notes: Valenzuela-Lopez et al. (2018) proposed Neopyrenochaeta to accommodate four species namely, N. acicola (Moug. & Lév.) Valenz.-Lopez et al., N. fragariae Valenz.-Lopez et al., N. inflorescentiae (Crous, Marinc. & M.J. Wingf.) Valenz.-Lopez et al. and N. telephoni (Roh. Sharma, Kurli, Sonawane, Shouche & Rahi) Valenz.-Lopez et al. The genus has similar morphology of conidiomata and conidia with Pyrenochaeta De Not., but differs in phylogeny. Three fresh collections from freshwater in Thailand showed close phylogenetic affinity with Neopyrenochaeta species. These three collections are introduced as new species viz. N. annellidica, N. chiangraiensis and N. maesuayensis
