description: C2: Puccinia adenocauli (Syd. & P. Syd.) J.X. Ji & Kakish., Mycotaxon 132: 144, 2017. (Fig. 5)   
 Description:— Spermogonia subepidermal, flask-shaped, type 4 of Cummins & Hiratsuka (2003). Aecia subepidermal, erumpent, Aecidium-type with peridia and catenulate spores. Peridial cells firmly conjunct, cubic to polygonal, hyaline. Aeciospores catenulate, globose, obovoid or sometimes angular, 14–23 × 10–16 μm (av. 18 × 13 μm); walls hyaline, 0.6 μm thick, verrucose with big granules. Uredinia subepidermal, pale yellow, erumpent, without paraphyses. Urediniospores pedicellate, obovoid or ellipsoid, 17–25 × 13–18 μm (av. 21 × 15 μm); walls hyaline, echinulate, 1.6–1.2 μm (av. 0.9 μm), germ pores obscure. Telia subepidermal, erumpent, dark brown to black. Teliospores 2-celled by transverse septa, borne singly on pedicels, clavate to oblong with a round to obtuse apices and attenuate toward bases, constricted at septa, 21–45 × 7–20 μm (av. 32 × 10 μm); walls dark brown, smooth, 0.9 μm (av. 0.9 μm) thick, thickened at apices.

 Hosts and distribution in northeastern CHINA (Fig. 1): —Spermogonia and aecia on Adenocaulon himalaicum (Asteraceae) (A, B, C). Uredinia and telia on Carex onoei (A, B).   
 Note: —The life cycle of this species in China was confirmed by Ji et al. (2017). Morphological characteristics and host relations of this species are similar to those of P. carici-adenocauli Kakish., Yokoi & Harada (Kakishima et al. 1999, Azbukina 2005, 2015). However, P. carici-adenocauli was renamed as P. adenocauli based on Aecidium adenocauli Syd. & P. Syd. according to the International Code of Nomenclature (Melbourne Code 2012) (Ji et al. 2017). Spermogonial and aecial stages of this species on Adenocaulon, which are commonly found on the forest floor of hills and mountains in this area during spring to early summer.
