Uromyces pisi-sativi is well-known for infecting
Euphorbia cyparissias - here however you see the fungus on two other Euphorbia species: in this habitat, locally only those two Euphorbiae are present - and of both there exist infected individuals.Infected ones look completely different from non-infected plants, they remain sterile and won't even develop flowering buds; and they all show on the underside of leaves the marks of
Uromyces (see
second shot).For U. pisi-sativi there's a long list of synonyms -
