Habitat
Hardpacked dirt of footpath/fire trail, with Trifolium, graminoids, etc. I think the infected plants are Lepidium, but I'm not sure. A few plants had this weird white infection on the tips of their leaves--CJR5460.
Description
Uncommon, local. Most plants were only a little infected, so were hard to find.
