Abstract

Soybean (Glycine max) is a major source of edible oil and protein. A novel species of the genus Pythium, Pythium huanghuaiense, isolated from soybean seedlings in China, is described and illustrated on the basis of morphological characters and molecular evidence.
Pythium huanghuaiense sp. nov. is closely related to species of the genus Pythium in clade F, as evidenced by the presence of hyphal swellings and its relatively rapid morphological growth. However, it differs by having relatively small sporangia and plerotic or nearly plerotic and thin-walled oospores. A pathogenicity test confirmed the newly-identified species as a pathogen of soybean.
