Notes.

This species is recently described from Xinjiang Autonomous Region, China, under Picea schrenkiana Fisch. & C.A. Mey. So far it is known only from the type locality. Balsamia guozigouensis can be recognized by its distinctly warty ascomata, solid gleba with small and irregular chamber and irregularly clavate asci. Phylogenetically, it was closely related to B. luyashanensis (Fig. 2 ), but the latter differs in its ascomata with fine warts and gleba without chambers ( Xu et al. 2018).

Figure 2. Phylogenetic tree generated from Bayesian analysis based on ITS sequences, showing the phylogenetic relationships of Balsamia. Tuber anniae and T. bellisporum are the outgroups. Maximum parsimonious bootstrap support values (≥ 70 %) and maximum likelihood bootstrap support values (≥ 70 %) are indicated above the nodes as MPBS / MLBS. Thick black branches received Bayesian posterior probabilities (BPP) ≥ 0.95. Novel sequences are printed in bold.
