(Hon, Shi, Kyu); II, III on Carex humilis Leyss. var. nana (H.Lév. & Vaniot) Ohwi (= C. nanella Ohwi ) (Hon), Carex lanceolata Boott (Hok, Hon, Kyu) ( Ito 1950, Harada 1984, Hiratsuka 1960, Hiratsuka et al. 1992).

Notes:— Aecidium atractylidis is the legitimate earliest name of this species. Therefore, a new combination name, based on this anamorphic species name, should be proposed under the ICNafp Shenzhen Code ( Turland et al. 2018). Because Puccinia atractylidis P. Syd. & Syd. is a preoccupied available name a new name, P. aomoriensis-caricis , is proposed as a replacement name for this species to avoid taxonomic confusion. This species has been reported from China, Korea and Russian Far East ( Ito 1950, Hiratsuka 1960, 1963, Tai 1979, Hiratsuka et al. 1992, Zhuang et al. 1998, Azbukina 2005, Ono 2019).
