Type species – Phaeopoacea festucae Dissanayake & K.D. Hyde, in Thambugala et al., Mycosphere 8(4): 752 (2017).
Notes – Thambugala et al. (2017b) introduced the new genus Phaeopoacea to accommodate P. festucae and P. phragmiticola (≡ Phaeosphaeria phragmiticola). The type species of Phaeopoacea, P. festucae has been known only from the asexual morph forming pycnidial conidiomata, globose to subglobose, or linear in rows on the host, and didymosporous, brown to dark brown, oblong conidia (Thambugala et al. 2017b). Whereas, Phaeosphaeria phragmiticola was previously treated as a synonym of Septoriella leuchtmannii by Crous et al. (2015a). Based on multi-gene phylogenetic analyses obtained by Li et al. (2015) and Thambugala et al. (2017b), Phaeosphaeria phragmiticola was accommodated in Phaeopoacea. The other two species, P. asparagicola and P. muriformis were later included by Hyde et al. (2017, 2019). Phaeopoacea does not form a well-resolved clade and always clustered in a problematic clade with the genera Allophaeosphaeria, Amarenographium, Amarenomyces, Dactylidina, Poaceicola, Septoriella and Vagicola (Hyde et al. 2017, 2019, 2020b, Thambugala et al. 2017b, Wanasinghe et al. 2018c, Phookamsak et al. 2019). More taxon sampling and reliable genes are acquired to resolve these generic affinities.
