Puccinia karstenii Lindroth, 1901
No host plant alternation; telia only. These brown, on the petioles and (the underside of) the leaves on discoloured and galled spots. Spores two-celled, on short, deciduous pedicels. The germination pore of the lower cell usually is located in the upper half of the cell (contrary to P. angelicae, where it is the other way).
Apiaceae, narrowly monophagous
