Description

The fungus appears as very fine, fragile mycelium on the leaves of its host. Golovinomyces calceolariae, like most Erysiphaceae, is highly host-specific and infects only two genera. The species on North American Galium is Golovinomyces galiorum which is also noticeably more robust.^[1] In Europe, other species such as Golovinomyces riedlianus and Neoerysiphe galii can be found (the latter may potentially be introduced to North America).

Taxonomy

The fungus was formally described in 2009 by Havrylenko, S. Takamatsu & V.P. Heluta.^[2] The specific epithet derives from the host genus of the holotype.
