Ramularia Unger
(a genus of plant-pathogenic anamorphic hyphomycetes)

A large form genus of anamorphic obligate plant necrotrophs which cause pale brown, grey or whitish leaf-spots on living leaves. Under a hand lens, white bunches of conidiophores can be seen emerging through the stomata, usually on the lower leaf surface. Under the microscope, the hyaline, cylindric conidia have prominent attachment scars, and in some species, one or more septa.

Ramularia anamorphs are host specific on a wide range of mostly herbaceous plants.

The teleomorphs, where known, are Mycosphaerella spp.
