Puccinia breviculmis Dietel

Heterotypic synonym:— Uredo breviculmis Henn., Hedwigia Beiblätter 40: (125), 1901 [MB229755].

Type:— Lectotype is selected from specimens in S and designated here: II, III on Carex leucochlora Bunge var. leucochlora , Japan, Tokyo, December 1904, N. Nambu, S (F31987), [MBT10021409]. Paratypes in S (F31988) and TNS (F113881).

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

Hosts and distribution in Japan:— II, III on Carex leucochlora Bunge var. leucochlora [= C. breviculmis var.

leucochlora (Bunge) Makino, C. royleana Nees ex Wight ] (Hon, Shi, Kyu, Ryu), C. leucochlora var. gracillima (Akiyama) Katsuy. (= C. filiculmis Akiyama ) (Hok, Hon, Ryu) ( Ito 1950, Hiratsuka 1960, Hiratsuka et al. 1992).

Notes:— Uredo breviculmis is the legitimate earliest name of this species. Therefore, this specific epithet is combined to the genus Puccinia to obtain an appropriate species name for it according to the ICNafp Shenzhen Code ( Turland et al. 2018). However, Puccinia breviculmis Dietel (1907) has been independently described based on its teleomorphic stage, and preoccupied. Hiratsuka et al. (1992) treated Uredo breviculmis as an anamorph of this teleomorphic species and the name of teleomorph has also been long used. From these circumstances, Puccinia breviculmis Dietel is applied for its appropriate species name as a heterotypic synonym of Uredo breviculmis Henn. following Art. F.8.1, ICNafp Shenzhen Code ( Turland et al. 2018). This species is widely recorded in Japan, but its spermogonial and aecial stages have not been found. This species is also reported from Taiwan ( Tai 1979, Hiratsuka & Chen 1991, Zhuang et al. 1998).
