Type species – Petriella asymmetrica Curzi
Notes – Petriella resembles Microascus but was segregated from Microascus by its hairy ascomata. The ascospores in Petriella are also larger than most other genera in Microascales. The genus was accepted in Microascaceae by Kirk et al. (2013), Sandoval-Denis et al. (2016a), Maharachchikumbura et al. (2015, 2016b) and Wijayawardene et al. (2017a, 2018a).
