Subclass Pleosporomycetidae C.L. Schoch et al.
Pleosporomycetidae was introduced as a subclass by Schoch et al. (2006) and included the single order Pleosporales. Subsequently, Schoch et al. (2009a) included the two other orders Mytilinidiales and Hysteriales within this subclass, and suggested that the order Jahnulales can be tentatively included within Pleosporomycetidae. Hyde et al. (2013) showed similar results, however the newly introduced order Dyfrolomycetales and Strigulales, and Acrospermales clustered together with Jahnulales. Because the lack of strong phylogenetic evidence, we only accept Pleosporales, Mytilinidiales and Hysteriales representing the subclass Pleosporomycetidae.
