Abstract
Ornamental roses worldwide harbor 10Phragmidium species. Among theseP. americanum, P. fusiforme, P. montivagum, P. mucronatum, P. rosae-pimpinellifoliae, P. rosae-rugosae andP. tuberculatum are frequently reported; however, these species are morphologically similar and difficult to distinguish. For better circumscription and correct identification of the species, this study examined morphological features in urediniospores and teliospores of the sevenPhragmidium species collected on ornamental rose cultivars and wild species. The results indicated that some host-specific groups could be well circumscribed by the morphological properties of urediniospores and teliospores. However, without the precise identification of hosts, these morphological properties were not effective key characters for the identification of the species.
