Tanay how about *Uromyces tuberculatus<http://www.cybertruffle.org.uk/cgi-bin/robi.pl?location=UN&assorg=279030&assoge=&glo=eng&link=&organism=14187>, it* is reported from Euphorbia helioscopia. I remember the name of Uromyces associated with Euphorbia helioscopia when I was in Kashmir. This weed is abundant Kashmir University campus, and turns wholly yellow with yellow rust in autumn.
