Classification: Microascaceae, Microascales, Hypocreomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi.

Petriella is morphologically closely resembling with Microascus (Zukal 1885), but differs by having hairy ascomata (Curzi 1930). Petriella is typified by P. asymmetrica Curzi and currently this genus comprises seven species (Index Fungorum 2023). Petriella was accepted in Microascaceae (Maharachchikumbura et al. 2015, 2016b; Wijayawardene et al. 2017, 2018; Hyde et al. (2020c). Petriella species were collected as saprobes on dried branches of Pyrus communis, Populus grandidentata, P. nigra and on leaves of Luzula sp. from China (Honshu), Cyprus, Italy, Thailand and USA (Ontario) and on the dung of Cervidae from USA (Ontario) (Corlett and MacLatchy 1987; Lackner and de Hoog 2011). This study introduces a new Petriella species.

Type species: Petriella thailandica O. Karimi & K.D. Hyde.

Other accepted species: Species Fungorum – search Petriella.
