Description
The fungus forms thin, white irregular patches on the leaves, stems and bracts of its host. Despite formerly being thought to infect a vast array of distantly related plants, Golovinomyces cichoracearum, like most Erysiphaceae, is highly host-specific and infects only two genera.[1] It is also likely to infect Pseudopodospermum and Scorzoneroides, although infections on these hosts are unconfirmed.
Taxonomy
The fungus was formally described in 1805 by de Candolle.[2]
