Etymology.

Named after the location where it was collected, Jingdong Yizu Autonomous County.

Description.

Sexual morph: undetermined. Asexual morph: Pycnidia smooth, subglobose, pale brown. Conidia ellipsoidal to subcylindrical, pale yellow, smooth, generated from pycnidia, aseptate, 7.1–16 × 4–9 µm (av. = 10.7 ± 1.2 × 5.4 ± 0.6 µm, n = 30). Mycelia extensively branched from subapical hyphal compartments, septate, hyaline.

Culture characteristics.

Colonies on PDA reaching 35–42 mm diam. after 7 days at 28 ° C in the dark, margin irregular, aerial mycelium flat, pale brown to rosy, white edges; reverse black to brown, pale buff edges. Pycnidia and conidia produced on the colony surface after being cultured for 14 days at 28 ° C in the dark. Colonies on OA reaching 49–55 mm diam. after 7 days at 28 ° C in the dark, margin regular, aerial mycelium flat, pale buff to whitish; reverse concolorous.

Materials examined.

China, Yunnan Province, Puer City, Jingdong Yizu Autonomous County, from healthy leaves of C. sinensis, 13 Jun 2020, Y. C. Wang, Holotype HMAS 352389, culture ex-type CGMCC 3.24247 = YCW 1868 . Yunnan Province, Puer City, Jingdong Yizu Autonomous County, from healthy leaves of C. sinensis, 13 Jun 2020, Y. C. Wang, culture ex-type CGMCC 3.24248 = YCW 1937 .

Notes.

Epicoccum jingdongense is closely related to E. dendrobii and E. puerense with high statistical support (83 % / 0.99, ML / PP, Fig. 3). Epicoccum puerense differs in 1 bp in ITS and 40 bp in TUB 2 from E. dendrobii . The conidia size is larger than that of E. dendrobii . In the present study, six strains were isolated from healthy tea plant leaves. It was isolated and identified from tea plant for the first time.
