Blumeria is a genus of plant pathogenic fungi in the family Erysiphaceae (powdery mildews). Members of the genus are found on all continents bar Antarctica and infect members of the Poaceae (grasses).[1]
Blumeria species form thick mycelial growth on the leaves of their hosts. Depending on the species and the stage of infection, the mycelium can be white, grey, tan or brown. When present, the chasmothecia are often densely packed. Some species infect staple crops such as wheat and barley, and these have been the subject of numerous genomic and resistance analyses in order to determine a way of ensuring crop resistance to the powdery mildew.[2]
