Phragmidium fusiformeL teliospores

Rosa pendulina, from González-Fragoso (1925a): teliospores


no alternation of hostplant. Spermogonia mostly epiphyllous, between epidermis and cuticula. Aecia hypophyllous, orange, extensive pads, without a peridium but with a coronet of hyaline, sausage-shaped curved paraphyses; spores produced in chains, separated by intercalar cells, spinulose. Uredinia like the aecia but smaller, spores single, pedicellate. Teliospores develop in the uredinia: long pedicellate, fusiform (tapering towards the apiculus), dark brown, transversely divided into c.10-12, coarsely verrucose cells, top cell gradually tapering into an apiculus.


Rosaceae, monophagous
