Uromyces graminis (Niesl) Dietel, 1892

on Apiaceae

gall

Spermogonia between the aecia, eventually honey-coloured. Aecia mostly hypophyllous, on strongly swollen parts of the leaf; they appear as warts, with the peridium extending through an apical pore. Spores pale yellow, thick-walled (up to 3 µm), very densely fine-verruculose, with 3-6 pores covered by a low papilla.
