Treatment

Colletotrichum boninense Moriwaki, Toy. Sato & Tsukib. , Mycoscience 44 (1): 48 (2003)

= Colletotrichum fici Tennakoon, C. H. Kuo & K. D. Hyde , Fungal Diversity 108: 158 (2021)

Material examined.

China • Yunnan Province, Dali , Symptomatic fruit of Juglans regia L., 2023.11. 12, Zhou Mengting, DJ 16-7 / GZ 01 / GZ 01-2 (dried culture, HGUP 25-0044 ), living culture GUCC 25-0020 , GUCC 25-0059 .

Hosts and distribution.

Damm et al. (2012), Zhang et al. (2024).

Notes.

In the phylogenetic tree (Fig. 1 View Figure 1 ), C. fici (strains MFLU 18-2615 , NCYUCC 19-0336 , and NCYUCC 19-0337 ) clusters within the C. boninense s. str. clade. When C. fici was originally described, the study lacked comprehensive taxon sampling within the C. boninense complex and included only the type strain of C. boninense s. str. Additionally, the molecular data for C. fici were limited to ITS, act, and chs- 1 loci ( Tennakoon et al. 2021). Pairwise comparisons between C. fici and the type strain of C. boninense s. str. showed less nucleotide differences: ITS = 1 / 553 (0.2 %), act = 2 / 269 (0.74 %), and chs- 1 = 1 / 245 (0.4 %). These differences fall within the range of intraspecific variation. Therefore, based on both phylogenetic and molecular evidence, C. fici is herein regarded as a synonym of C. boninense s. str. Additionally, in this study, strains GUCC 25-0020 and GUCC 25-0059 , isolated from Juglans regia in Kunming, China, were identified as Colletotrichum boninense based on phylogenetic analysis (Fig. 1 View Figure 1 ), with strong phylogenetic support (99 % BSML, 0.98 PPBI).
