# Isaria

Isaria is a genus of fungi mostly in the order Hypocreales and family Clavicipitaceae, or by some authorities the Cordycipitaceae. It includes a large number of entomopathogenic species, some of them exploited as biopesticides (e.g. I. fumosorosea): often previously assigned to the genus Paecilomyces.
The teleomorph of this genus appears to be Ophiocordyceps.
