Pseudofusicoccum Mohali, Slippers & M.J. Wingf., Stud. Mycol. 55: 249 (2006).
Index Fungorum number: IF 500884; Facesoffungi number: FoF 05299, 8 morphological species (Species fungorum 2021), 7 species with molecular data.
Pathogenic on host. Sexual morph: Unknown. Asexual morph: Conidiomata large, superficial on MEA, multilocular, eustromatic, covered with hyphae; locule totally embedded without ostioles, locule walls consisting of a dark brown textura angularis, becoming thinner and hyaline towards the conidiogenous region. Conidiogenous cells hyaline, holoblastic, smooth, cylindrical, producing a single apical conidium, the first conidium produced holoblastically and subsequent conidia produced enteroblastically. Conidia hyaline, thin to slightly thickened walled, aseptate, granular, bacilliform, straight to slightly curved, apex and base both bluntly rounded or just blunt (Adapted from Mohali et al. 2006).
Type species: Pseudofusicoccum stromaticum (Mohali, Slippers & M.J. Wingf.) Mohali, Slippers & M.J. Wingf.
Notes: Pseudofusicoccum was introduced by Mohali et al. (2006) with P. stromaticum as type species. Pseudofusicoccum is characterized by multilocular, eustromatic conidiomata, peridium comprising dark brown cells of textura angularis, holoblastic conidiogenous cells and hyaline aseptate conidia. Crous et al. (2006a) identified a mucous layer around conidia of all Fusicoccum species and accommodated these species in Pseudofusicoccum. Pseudofusicoccum differs from Fusicoccum by the production of a pigment in culture and the size of conidia (Pavlic et al. 2008). Since then, several new species have been introduced by different authors based on morphology and phylogeny (Mehl et al. 2011; Trakunyingcharoen et al. 2015; Jami et al. 2018). Yang et al. (2017) raised Pseudofusicoccum to familial status as Pseudofusicoccaceae. In the phylogenetic analyses of Phillips et al. (2019), Minnis et al. (2012) and Liu et al. (2017), Pseudofusicoccum clustered in the same clade as members of Phyllosticta. Phillips et al. (2019) considered Pseudofusicoccum as an additional genus within Phyllostictaceae based on morphology, phylogeny and evolutionary divergence evidence.
