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.

González-Fragoso (1922a) mentions “Seseli glaucum”; according to the Plant List (2017) this is either Seseli montanum or Trinia glauca.
on Melica
