(3.3) Candolleomyces iqbalii complex

Notes:— In the ITS-only phylogeny ( Fig. 4B ), one collection of ours, three collections labeled as Candolleomyces iqbalii , and two collections labeled as Cd. punjabensis (Nom. ined.) established a monophyletic group without significant support. None of these collections has four-locus data. This group is referred to as Candolleomyces iqbalii complex in this study, characterized by usually slender basidiomata with brownish pileus, and a terrestrial to lignicolous habit. Based on the recent scale of species delimitation within Candolleomyces in academia, one undescribed species appears to exist within this complex.

Legitimately proposed species recognized in this complex:— Cd. iqbalii Usman, Bibi, Afshan & Khalid (2024) .

Collection sequenced in this study:— China, Guangdong Province, Guangzhou City, elevation 30 m, 2023, Jia Y. Lin, L23435 ( HTBM1416 ).

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.
