Puccinia oerteliana Tranzschel, 1923

on Geranium

gall

no host plant alternation known, only spermogonia and aecia. Spermogonia very rarely formed, amphigenous. Aecia hypophyllous on large, red, galled spots; they are sunken in the leaf tissue, with a small opening; the peridium is stellate, soon falling off.

hostplants

Geraniaceae, narrowly monophagous

Geranium sanguineum.

synonyms

Aecidium tranzschelianum Lindroth, 1901.

notes

because the aecia show a strong resemblance with the ones of Puccinia stipina, a species forming aecia on various Lamiaceae, and telia on Stipa, one supposes that oerteliana likewise forms telia on Stipa.
