Acrodictys was introduced to accommodate species having conidiophores often with successive terminal proliferations, and variable-shaped, dictyoseptate, pale brown to dark blackish brown conidia (Ellis 1961). The type species A. bambusicola was initially collected in Venezuela (Ellis 1961), later collected and sequenced from China (Xia et al. 2017). Acrodictys is confused with Junewangia as both genera have long conidiophores with percurrent proliferations, and dictyoseptate conidia often with a protruding base (Xia et al. 2017). However, phylogenetic analysis places them in Acrodictyaceae and Junewangiaceae, respectively. The latest treatment was carried out by Luo et al. (2019), who introduced a new species A. fluminicola and a new combination A. aquatica in Acrodictys. We redescribe and illustrate A. porosiseptata in this study.
