For the ITS region, the closest matches were predominantly with uncultured environmental sequences, with the highest similarity to an uncultured fungus (GenBank accession no. HM 030609) at 97.2 % similarity. Among named species, the closest match was with C. chlamydosporum (GenBank accession no. MH 858992) at 96.3 % similarity. The multi-gene phylogeny (Fig. 2) showed that C. chishuiensis is related to C. crousii, C. kirkii, C. tropicale, and C. xishuangbannaense . Pairwise comparisons of ITS sequences (gaps excluded) showed that C. chishuiensis differs from C. crousii, C. kirkii, C. tropicale, and C. xishuangbannaense by 9.3 % (45 / 482 bp), 2.9 % (14 / 482 bp), 7.5 % (36 / 482 bp), and 8.9 % (43 / 482 bp), respectively. The ITS sequence divergence between C. chishuiensis and related species is well above the 1.5 % threshold proposed by Jeewon and Hyde (2016) for species recognition.</p><p>Morphologically, Chloridium chishuiensis differs from C. crousii, C. tropicale, and C. xishuangbannaense in producing multiple conidiogenous loci within the collarettes, whereas the latter possess a single sporulating locus within the collarettes (Wu and Diao 2022). It resembles C. kirkii but can be distinguished by its longer conidiophores (88–155 × 2.5–5 µm vs. 22–65 × 2–2.5 µm) and guttulate conidia (Wu and Diao 2022). In addition, chlamydospores were not observed in this species. Consequently, C. chishuiensis is proposed here as a new species based on both molecular and morphological evidence.</p></div>	https://treatment.plazi.org/id/B67C21F345B454B0B66BCB63D19F7A38	Public Domain	No known copyright restrictions apply.

(2023). Later, Lin et al. (2025) reported its first occurrence in terrestrial habitats in Guizhou Province. In the present study, a fungal collection obtained from bamboo is examined. BLASTn analyses revealed that the ITS sequence shared 98.8 % similarity with the ex-type strain of R. aquimicrospora and 98.7 % – 100 % identity with other conspecific accessions, whereas the LSU sequence showed 99.6 % similarity to the ex-type and 99.8 % – 100 % identity among conspecific strains. Morphologically, it aligns with the description of R. aquimicrospora, although the synnemata in the specimen are shorter (105–150 µm) compared to the holotype (135–178 µm; Yang et al. 2023). Phylogenetic analysis placed the strain within a clade comprising other strains of R. aquimicrospora (Fig. 2). Sequence comparison of the LSU, ITS, and SSU regions between the strain and the ex-type strain (GZCC 20-0515) revealed 1 / 779 bp (0.13 %), 3 / 517 bp (0.58 %), and 0 / 907 bp differences, respectively. Based on morphological and molecular evidence, the collection is identified as Rhamphoriopsis aquimicrospora, which represents a new host record for this species.</p></div>	https://treatment.plazi.org/id/0DC7896ECAE95C4F9AAA3754E7CD6BCC	Public Domain	No known copyright restrictions apply.

Xylolentia chishuiensis is phylogenetically sister to X. oblongispora (GZCC 18-0054) with high support (ML - BS = 100 %, PP = 1) (Fig. 2). Morphologically, X. chishuiensis can be distinguished from X. oblongispora by its shorter and narrower conidiophores (80–110 × 3–4 μm vs. 91–219 × 3.5–8.5 μm) and its smaller, ellipsoidal to subglobose conidia (2.5–4 × 1.5–2.5 μm vs. 3.6–5.3 × 2.2–3.2 μm) (Lin et al. 2025). In contrast, X. oblongispora produces oblong conidia with obtuse ends and guttules (Lin et al. 2025). Additionally, the two species exhibit a difference of 17 / 502 base pairs (3.4 %, without gap) in the ITS region and 20 / 850 base pairs (2.4 %, without gap) in the tef 1 - α region. Based on this combined molecular and morphological evidence, Xylolentia chishuiensis is described as a new species.</p></div>	https://treatment.plazi.org/id/6AF86562CC455F868C72950E3CD07D2D	Public Domain	No known copyright restrictions apply.

Furthermore, a comparison of DNA sequence data shows that the strain is identical to the ex-type strain of X. yibinensis in the LSU and SSU regions but differs by 7 / 504 base pairs in the ITS region (1.39 %, without gaps) and 10 / 879 base pairs in the tef 1 - α region (1.14 %, without gaps).
