(3.8) Candolleomyces typhae complex

Notes:— In the ITS-only phylogeny ( Fig. 4B ), one collection of ours gathered on Musa sp. and one collection labeled as Candolleomyces typhae established a distinct monophyletic group with low internal variation by significant support, but it was uncertain whether they should be recognized as a single species based on the recent scale of species delimitation within Candolleomyces in academia. In the four-locus phylogeny ( Fig. 4A ), only the collection labeled as Cd. typhae with complete four-locus data was analysed for this group, and it formed a distinct, independent clade. This group is referred to as Candolleomyces typhae complex in this study, characterized by small basidiomata with a herbicolous habit.

Legitimately proposed species recognized in this complex:— Cd. typhae (Kalchbr.) D. Wächt. & A. Melzer (2020) .

Collection sequenced in this study:— China, Guangdong Province, Guangzhou City, elevation 20 m, 2024, Kun L. Yang & Hai-Feng Wu, K24020 ( HTBM1875 ) .

FIGURE 4. Phylogeny of Candolleomyces inferred from concatenated ITS-nrLSU-tef-1α-β-tub alignment (A; all samples with sequence data complete in the four loci) or ITS alignment (B). Nodes are annotated if supported by ≥50% MLB or ≥0.9 BPP. Branches shortened to fit the page are indicated by two diagonal lines, followed by the number of times shortened. Collections sequenced in this study are highlighted in gold. Holotypes, epitypes, and neotypes are indicated by HT, ET, and NT, respectively. Photos and line drawings of our collections, and species delimitation results are attached.
