Setosphaeria rostrata

Setosphaeria rostrata is a thermophilic fungus with an asexual reproductive form treated in the genus Exserohilum (as Exserohilum rostratum). This fungus is a common plant pathogen, causing leaf spots as well as crown rot and root rot in grasses. It is also found in soils and on textiles in subtropical and tropical regions. Exserohilum rostratum is one of the 35 Exserohilum species implicated uncommonly as opportunistic pathogens of humans where it is an etiologic agent of sinusitis, keratitis and CNS vasculitis as well as cutaneous and subcutaneous mycoses. Infections caused by Exserohilum are most often seen in regions with hot climates particularly Israel, India and Southern USA.
