Previously B. graminis was included within the genus Erysiphe, but molecular studies have placed it into a clade of its own. In 1975, it was moved to the new monospecific genus Blumeria. Blumeria differs from Erysiphe in its digitate haustoria and in details of the conidial wall. Blumeria is also considered to be phylogenetically distinct from Erisiphe as it solely infects the true grasses of Poaceae.
