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.
