Notes – Members of Pseudotrichia are characterized based on size and number of septa of their ascospores. This genus has been subjected to many revisions. Based on ascomatal and peridial characters, the genus was accommodated in Didymosphaeriaceae (Thambugala et al. 2014b), and later moved to Melanommataceae based on multi-gene analysis (Liu et al. 2015). Based on multi- gene phylogenetic analysis, Pseudotrichia was excluded from Melanommataceae and repositioned in Pleomassariaceae (Tian et al. 2015). Due to the high morphological and phylogenetic diversity, some species in this genus have been excluded and repositioned in a new genus Thysanolaenae in Didymosphaeriaceae (Tian et al. 2015). The genus consists of mainly terrestrial saprobes with a cosmopolitan distribution (see Wijayawardene et al. 2018, outline).
