Xylochrysis aquatica is easily distinguished from the type species X. lucida by solitary, scattered, smaller ascomata (160 – 265 µm × 145 – 290 µm vs. 350 – 500 µm × 350 – 500 µm) without a layer of colored cells surrounded, longer asci (60 – 120 µm long vs. 59 – 73 µm long) and more rounded ascospores (L / W: 1.5 – 2.5 µm vs. 2.2 – 2.8 µm). Ascomata of X. lucida often aggregated or confluent in groups of 3 – 10 and surrounded by a golden yellow layer of cells. In addition, the ostiolar neck of X. lucida is short-beaked and distinctly longer (Réblová et al. 2014) than our new taxon, X. aquatica. The multi-gene (ITS-LSU-SSU- tef 1 - α - rpb 2) phylogenetic analyses suggested that our isolate clustered together with the generic type X. lucida and formed a distinct lineage (100 % ML; 1.00 PP) in Woswasiaceae. In addition, a nucleotide comparison of X. aquatica (CGMCC 3.23639) and X. lucida (CBS 135996) revealed 25 basepair (5 %) and 70 base-pair (7.2 %) differences in ITS (+ 5.8 S) and rpb 2, respectively (TABLE 2). Xylochrysis aquatica is introduced as a new species based on the moprhology and phylogeny evidences.	en	Song, Jing-Yi, Yang, Yi, Yu, Xian-Dong, Dissanayake, Asha J., Tian, Qing (2023): Xylochrysis aquatica sp. nov.
