Specimen examined.

CHINA • Zhejiang Province: Tianmu Mountain National Nature Reserve , 30.3234°N, 119.4538°E, on rotten wood, 18 Jun 2014, collected by Wen-Long Song and Ya-Jing Chen ( HFNNU 9995 ) .

Distribution.

Ukraine, Russia, Germany ( Leontyev et al. 2023 b), Norway ( Johannesen and Vetlesen 2024), and China (this study).

Notes.

Lycogala alisaulianovae is recorded in China for the first time. The main characteristics of this species are copper or umber brown sporocarps, solitary peridial vesicles that appear dark brown under TL, and bluish-gray spore mass, which makes it easy to identify ( Leontyev et al. 2023 b). Our specimen HFNNU 9995 shows slight differences from the original description ( Leontyev et al. 2023 b) in terms of the color of the sporocarp (brown to nearly black) and the pigmentation of the vesicles (brownish yellow), but the capillitium, spore mass color, and spore ornamentation (Fig. 3 ) are the same as those of the original description. The two-gene phylogenetic analysis (Fig. 2 ) clustered our specimen HFNNU 9995 within the branch of L. alisaulianovae (CWP 3656, IY 07, IY 26, sc 27822, sc 32540, and sc 32527) with high statistical support (UBS = 100, PP = 1), thus confirming its morphological identification as L. alisaulianovae .

Figure 2. Maximum likelihood tree inferred from the concatenated sequences of SSU and COI, showing the phylogenetic relationship of Lycogala. The members of Reticularia were used to root the tree. Only Maximum likelihood ultrafast bootstrap support (UBS) / Bayesian posterior probabilities (PP) ≥ 70 / 0.7 are shown. The voucher numbers are indicated after the species names. The number of identical genotypes is in parentheses (if present). The ten new species described in this study are indicated in red and bold. The four new species to China are indicated in blue and bold. Other newly obtained sequences are in bold. The scale bar represents the number of substitutions per site.
