Type speciesPseudallescheria shearii Negroni & I. Fisch.

NotePseudallescheria species are saprobes worldwide and have been isolated from soil, sewage, contaminated water, and the manure of farm animals. Species are also opportunistic pathogens that can cause various infections in humans. The genus was accepted in Microascaceae by Kirk et al. (2013), Sandoval-Denis et al. (2016a), Maharachchikumbura et al. (2015, 2016b) and Wijayawardene et al. (2017a, 2018a). The asexual morphs of Pseudallescheria are undetermined, however, scedosporium-like and graphium-like taxa are probably linked.
