Erysiphe alliariicola is a species of powdery mildew in the family Erysiphaceae. It is found on plants in the genus Alliaria in Eurasia and North America (where A. petiolata is an invasive species)[1] as well as occasionally on Thlaspi.
Description
The fungus forms thin, white irregular patches on the leaves of its host. Erysiphe alliariicola, like most Erysiphaceae, is highly host-specific and only infects two genera. It is the only species to infect Alliaria.[2] It has also been reported as infecting Thlaspi in North America.[3]
Taxonomy
The fungus was formally described in 2024 by Michael Bradshaw and Uwe Braun. The species epithet refers to the host genus, Alliaria. The type specimen was collected in Germany.[4] E. alliariicola was formerly considered conspecific with Erysiphe crucifearum but was split from this species on the basis of genetic analysis.[2]
