Rubus caesius, uit González-Fragoso (1925a): uredinium (doorsnede)

Kuehneola uredinis: uredinium

Rubus caesius, from González-Fragoso (1925a): uredinium (section)

gal: Spermogonia bovenzijdige subcuticulaire wratjes. 0.2 mm, op rode vlekjes. Aecia bovenzijdig, geel. Uredinia onderzijdig, vaak het hele blad bestrijkend, vaak op de stengels en bladstelen, geel, gelijkend op de aecia. De uredinia zijn niet omringd door paraphysen, wat ze onderscheidt van die van de Phragmidium-soorten op braam. Telia (treden zeer weinig op) witte of gelige onderzijdige kussentjes, sporen in ketentjes van ca 5-7 cellen.

gall: Spermogonia epiphyllous subcuticular pustules, 0.2 mm, on red spots. Aecia epiphyllous, yellow. Uredinia hypophyllous, often extending over the entire leaf, often also on the stems and petioles, yellow, similar to the aecia. The uredinia are not sorrounded by praphyses, which distinguishes them from those of the Phragmidium species on bramble. Telia (occurring quite rarely) hypophyllous, pulvinate, yellow or white; spores in chains of c. 5-7 cells.
