Novopuccinia sycopsis-sinensis Y. Liu & Y. M. Liang, sp. nov. Figure 4

MycoBank number: MB 838357; Index Fungorum number: IF 838357; Facesoffungi number: FoF;

Typification: CHINA. Mt. Sanqingshan, Jiangxi Province, 28◦53r88rrN, 118◦04r57rrE, 1,340 m alt., April 1, 2017, on Sycopsis sinensis Oliv, coll. Y.M. Liang (Holotype: BJFC-R02976; Paratype: BJFC-R02983).

Etymology: Named after the host name of the type species.

Descriptions: Spermogonia, aecia, and uredinia unknown. Telia hypophyllous or petiolicolous, orange, hairlike columnar, exposed, and 2–5 mm long. Teliospores one-celled with elongated pedicel-like intercalary cells (25 µm long), ellipsoid to obovoid, 20–35 9–14 µm, and attenuate toward both ends; cytoplasm yellow; the wall colorless, 0.5–1 µm thick, and densely verrucose. Peridium cells rectangular to rounded, 20–31 18–23 µm; the wall colorless, 3–5 µm thick, and rough-surfaced.

Notes: N. sycopsis-sinensis can be easily distinguished from other similar taxa by elongated pedicel-like intercalary cells, one- celled, and peridium cells (Figure 4). According to Tranzschel’s law, the species has an endocyclic life cycle (Buriticá and Hennen, 1980; Buriticá, 1991).
