A new fungal species, Phoma heteroderae, was isolated and described from Heterodera glycines, the soybean cyst nematode. The fungus can be distinguished from other species of the genus by a combination of the following characteristics: pycnidia thin-walled, with neck short or lacking, ostiolate, often with setalike hyphal outgrowth; conidia aseptate, 4.5-7.3(-11.8) x 2.4-3.7(-4.5) μm; chlamydospores subhyaline to brown, unicellular, terminal, lateral, or intercalary. The fungus appears to be a weak parasite of H. glycines eggs.
