Puccinia silvatica J. Schröt.

Homotypic synonym:— Dicaeoma silvaticum (J. Schröt.) Syd.

Type:—Location of the holotype specimen has not been found. Isotype in BPI (102864).

Description:—See Hiratsuka et al. (1992).

Hosts and distribution in Japan:— II, III on Carex middendorffii F. Schmidt var. middendorffii (Hok, Hon) , C. leucochlora Bunge var. leucochlora [= C. breviculmis var. leucochlora (Bunge) Makino , C. royleana Nees ex Wight ] (Hon) ( Ito 1950, Hiratsuka 1960, Morimoto 1961, Hiratsuka et al. 1992).

Notes:—Spermogonial and aecial stages have been reported as Aecidium species ( A. asterum Schwein. , A. senecionis Desm. , A. taraxaci J.C. Schmidt & Kunze , etc.) on species of Asteraceae ( Aster , Taraxacum , Crepis , Senecio , etc.) ( Hiratsuka et al. 1992, Zhuang et al. 1998). Miura (1928) reported occurrence of these stages on Ixeris species in Japan by inoculations ( Ito 1950) and their morphological similarities with A. compositarum Wallr. However , these stages of this species need to be reconfirmed. Taxonomic relationships of this species with Puccinia dioicae Magnus and P. extensicola Plowr. also should be clarified because similarities of morphology and life cycle ( Zhuang et al. 1998, Azbukina 2005). This species is widely distributed in Europe, North America and East Asia including China and Russian Far East. ( Zhuang et al. 1998, Azbukina 2005).
