Epicoccum latusicollum Q. Chen et al. , Studies in Mycology. 87: 144. 2017

Description.

see Chen et al. (2017).

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 1921 .

Notes.

Isolates of Epicoccum latusicollum were clustered into a sister clade to E. poaceicola and E. sorghi (Fig. 3 ). Pycnidia were black-brown and mostly spheroid and conidia were ellipsoidal to oblong, aseptate and hyaline ( Chen et al. 2017; Li et al. 2023). It was first discovered from Acer palmatum ( Aceraceae ), Camellia sinensis ( Theaceae ), Podocarpus macrophyllus ( Podocarpaceae ) and Vitex negundo ( Verbenaceae ) ( Chen et al. 2017). As a phytopathogen, it can cause leaf spot, leaf blight and stalk rot on many plants ( Xu et al. 2022; Li et al. 2023; Wang et al. 2023). In the present study, three strains were isolated from healthy tea plant leaves.

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.
