Type species – Pseudostaurosphaeria chromolaenicola Mapook & K.D. Hyde, in Mapook et al. Fungal Diversity 101: 82 (2020).
Notes – Pseudostaurosphaeria was introduced by Mapook et al. (2020) to accommodate the coelomycetous asexual taxa collected from Chromolaena odorata in Thailand. The genus is morphologically similar to Staurosphaeria in Coniothyriaceae but is phylogenetic distinct (Wanasinghe et al. 2017a, Mapook et al. 2020). Pseudostaurosphaeria forms a well-resolved clade and is sister to Yunnanensis. However, the genus can be distinguished from Yunnanensis in having subglobose to obovoid, muriform 2–4-celled conidia, with a single polar appendage from apex (Mapook et al. 2020). Whereas, Yunnanensis has ellipsoidal to obovoid, 3 transverse septa, with 1 longitudinal septum, at the 2nd and the 3rd cell and lacking appendage (Karunarathna et al. 2017a).
