Abstract
In 2008, a powdery mildew on Eustoma grandiflorum collected in Corrientes, Argentina was determined to belong to Oidium subgenus Pseudoidium. The diagnostic features of the anamorph were recorded, but the teleomorphic state of this fungus was not found. This is the first report of Oidium subgenus Pseudoidium affecting E. grandiflorum in Argentina.
