Pyrenophora seminiperda is a minor plant pathogen that causes leaf spots on many grasses. It is an important generalist grass seed pathogen which causes visible cylindrical masses of black fungal hyphae (stromata) to grow from infected seeds. Hence the common name "black fingers of death"
It has been hypothesized that the fungus arrived in North America with invasive grasses from Eurasia. BFOD has been suggested as a method of biocontrol of the invasive cheatgrass, one of the most important invasive species in the USA., a secondary metabolite of the fungus, appears to be responsible for the seed killing.
