4 Known Hosts
Avena sativa
oat
Pathway not proven
RICH ISTA, USDA-FD, DILOAL-3
Though reported once that the fungus may be independent of the Anguina nematode seed galls, this fungus is usually associated with seed galls.
Removing nematode seed galls prevents issues with the disease caused by this pathogen.
