aecia also develop on the petioles, inducing strong galling

Puccinia urticae-caricis Klebahn, 1899.

Many authors consider all rusts alternating between Urtica and Carex species one, albeit variable species, urticata. Based on biological differences, and currently also DNA-structure, others see a complex of autonomous species. At the aecial stage they cannot be distinguished morphologically, but at the telial stage they can be distinguished based on the host plant and small morphological differences. The name “urticata” then stands for the entire complex of species.
