Epicoccum oryzae S. Ito & Iwadare, Report of the Hokkaido Prefectural Agricultural Experiment Station 31: 1. 1934

Description.

see Hou et al. (2020 b).

Materials examined.

China, Yunnan Province, Puer City, Jingdong Yizu Autonomous County, from healthy leaves of C. sinensis , 13 Jun 2020, Y. C. Wang, culture YCW 2010 .

Notes.

Epicoccum oryzae was synonymised as E. nigrum previously ( Schol – Schwarz 1959). It was resurrected as a separate species, distant from E. nigrum and CBS 173.34 was proposed as the ex-neotype of E. oryzae ( Hou et al. 2020 b) . Epicoccum oryzae is characterised by “ olivaceous hyphae, globose or subglobose sporodochia and globose, subglobose or pyriform, granular, verrucose, olivaceous conidia, consisting of one to five cells ” ( Hou et al. 2020 b). It clustered into a sister clade to E. endophyticum and E. mackenziei (Fig. 3 ). In the present study, one isolate from healthy tea plant leaves grouped with E. draconis ( CBS 173.34 and CBS 174.34) with high statistical support (Fig. 3 ). This is the first report of E. oryzae isolated from C. sinensis .

Figures

Figure 3. Phylogenetic tree generated by Maximum Likelihood analysis, based on the combined ITS, LSU, RPB 2 and TUB 2 dataset of Epicoccum species. Bootstrap support values above 50 % and Bayesian posterior values above 0.75 are shown at each node (ML / PP). Pleiochaeta setosa CBS 118.25 / CBS 496.63 and Co. palmarum CBS 400.71 are used as outgroups. Ex-type strains are emphasised in bold.
