(3.4) Candolleomyces luteopallidus complex

Notes:— In the ITS-only phylogeny (Fig. 4B), two collections of ours and two collections labeled as Candolleomyces luteopallidus established a monophyletic group with internal pairwise variations around 1% by significant support. In the four-locus phylogeny (Fig. 4A), two of our collections and another collection with complete four-locus data were analysed for this group, and they formed a distinct monophyletic group with significant support. This group is referred to as the Candolleomyces luteopallidus complex in this study, characterized by typically slender basidiomata with a reddish-brown to brownish pileus and a terrestrial habit. Based on the recent scale of species delimitation within Candolleomyces in academia, two undescribed species appear to exist within this complex.

Legitimately proposed species recognized in this complex:— Cd. luteopallidus (A.H. Sm.) D. Wächt. & A. Melzer (2020) .

Collections sequenced in this study:— China, Guangdong Province, Guangzhou City, elevation 30 m, 2023, Jia Y. Lin, L23410 (HTBM1391) and L23455 (HTBM1436).
