Crous et al. (2006) introduced Pseudofusicoccum with the type P. stromaticum. Species of Pseudofusicoccum are morphologically similar to Fusicoccum and Neofusicoccum but phylogenetically distinct from both of these genera (Crous et al. 2006, Phillips et al. 2013). They exhibit as endophytes, saprobes or plant pathogens associated with diseases on stems, twigs, branches and leaves in various hosts and have a worldwide distribution (Mohali et al. 2006, Doilom et al. 2015, Jami et al. 2018, Senwanna et al. 2020). The asexual morph is characterized by immersed to superficial pycnidial conidiomata, and hyaline, aseptate, cylindrical to ellipsoid conidia (Pavlic et al. 2008, Yang et al. 2017, Phillips et al. 2019). The sexual morph is characterized as globose to subglobose spots of ascomata on the host surface consisting hyaline, clavate ascospores surrounded by a mucilaginous sheath (Senwanna et al. 2020).
