Phragmidium rosae-pimpinellifoliae: aecia on Rosa pimpinellifolia

Rosa pimpinellifolia, Bergen aan Zee. Often the aecia form large lumps, but in this case they were present only as tiny specks on a gall of Diplolepis cf. eglanteriae.

characteristically, the spore gradually narrows into the apiculus


no alternation of hostplant. Spermogonia and aecia mostly on branches or petioles, also the veins. Aecia can fuse to large lumps, without a peridium but around the margin with, in this species mostly just a few, hyaline, sausage-shaped curved paraphyses; spores produced in chains, finely spinulose. Uredinia hypophyllous, up to 0.2 mm, orange, surrounded by many paraphyses, spores single, pedicellate. Telia hypophyllous brown; spores long pedicellate, elliptic, dark brown, transversely divided into c. 6-8, finely verrucose or smooth cells, apically gradually tapering into an apiculus.

host plants
