039B878C9902FFDF9BE3FF65493BFD92.taxon	materials_examined	Holotype: HUEST 24.0068 Etymology: The epithet refers to where the collection was made, Sichuan Province. Saprobic on decaying twigs of an unidentified herbaceous plant. Sexual morph: Not observed. Asexual morph: Colonies on natural substrates effuse, scattered, or aggregated, hairy, brown, glistening. Conidiophores 93 – 130 × 4.0 – 5.0 (x = 115 × 4.5, n = 20) macronematous, mononematous, erect, solitary or in small groups, lower part straight, upper part flexuous, cylindrical, reddish brown, slightly paler towards the apex, septate, unbranched. Conidiogenous cells polyblastic, integrated, terminal and intercalary, determinate, sympodial, denticulate, flexuous, cylindrical, pale reddish brown to subhyaline. Conidia acropleurogenous, solitary, fusiform or narrowly obovoid, subhyaline to pale brown, 0 – 1 - septate, finely verrucose, 9.5 – 14.5 × 4.0 – 4.5 μm (x = 12 × 4.5 μm, n = 30). Culture characteristics: Single-spore isolation was repeated three times on PDA and WA media, and no germinated spore was observed. Material examined: CHINA. Sichuan Province, Chengdu City, Dujiangyan City, Longchi National Forest Park, 103 ° 38 ’ 46 E, 31 ° 0 ’ 11 ” N, elevation 702 m, on decaying branches of an unidentified herbaceous plant, 5 October 2021, Y. P. Chen and W. H. Tian, LC 64 (HUEST 24.0068, holotype) Notes: Our fungus exhibits the typical characteristics of Neomyrmecridium (Xu et al. 2023). In the multi-gene phylogenetic tree (FIGURE 1), specimen HUEST 24.0068 forms a distinct branch. Its ITS sequence shows the highest similarity to Neomyrmecridium sorbicola CBS 143433, but with only 91 % sequence identity (510 / 559, 8 gaps). Morphologically, HUEST 24.0068 and Neomyrmecridium sorbicola exhibit a similar conidial size dimension (7 – 15 × 4 – 5 μm), but the latter is characterized by the possession of appendages, a feature absent in HUEST 24.0068 (Crous et al. 2018). Therefore, the study proposed that the newly collected specimen be a new species to Neomyrmecridium, which is designated N. sichuanense.	en	Chen, Yanpeng, Liao, Yuechi, Shami, Ashwag, Alharbi, Nada K., Liu, Jian-Kui, Maharachchikumbura, Sajeewa S.

039B878C990DFFDF9BE3FDF6494FFA02.taxon	description	Culture characteristics: Single-spore isolation was repeated three times on culture media (PDA and WA), and no germinated spore was observed. Material examined: China, Sichuan Province, Chengdu City, Qionglai County, Nanmuxi, 103 ° 7 ’ 16 ” E, 30 ° 18 ’ N, elevation 775 m, on dried twigs of an unidentified woody plant, 24 August 2021, Y. P. Chen and Y. B Guo, NMX 07 (HUEST 01.0275). Notes: In the Index Fungorum (https: // indexfungorum. org / Names / Names. asp, accessed January 10, 2025, Paradiacheopsis includes eight accepted species, all of which were described before the 21 st century, with no molecular data available for any of their type materials. For our newly collected specimen, although we attempted to extract DNA directly from the fruiting bodies on natural substrates three times, all attempts were unsuccessful. Through a literature review, we compiled the spore characteristics of these eight species (TABLE 3). HUEST 01.0275 has pale brown spores, which are similar to those of Paradiacheopsis longipe, as well as in conidial size dimension (5 ‒ 7.5 μm vs. 7 – 8 µm diam.) (Hooff & Nannenga-Bremekamp 1996). Therefore, we identified the newly collected specimen (HUEST 01.0275), as Paradiacheopsis longipes. The species was first reported by Ukkola et al. (2001) from Hunan Province, China, but no morphological data were provided. This study reidentifies the species in Sichuan Province and offers detailed characterization and visualization.	en	Chen, Yanpeng, Liao, Yuechi, Shami, Ashwag, Alharbi, Nada K., Liu, Jian-Kui, Maharachchikumbura, Sajeewa S.

039B878C990FFFDD9BE3FF0F4804FC5A.taxon	description	Culture characteristics: Conidia germinated on PDA within 12 h at 25 ° C in darkness. Colonies white with a dense, uneven texture and a distinct brownish central area, with irregular and slightly raised margins, approximately 12 mm diam. on PDA after 4 weeks at 25 ° C; on the reverse side, bright orange, dense, and exhibits a radiating, slightly wrinkled texture with smooth and well-defined margins. Material examined: China, Sichuan Province, Aba Tibetan and Qiang Autonomous Prefecture, Li County, Miyaluo Scenic Resort, 102 ° 48 ’ 35 ” E, 31 ° 42 ’ 56 ” N, elevation 3207 m, on decaying branches of an unidentified woody plant, 19 October 2021, Y. P. Chen and W. H. Tian, MYL 57 (HUEST 24.0139), living culture UESTCC 24.0128. Notes: BLASTn analysis showed that our newly collected isolate UESTCC 24.0128 displayed 99 % sequence identity of ITS (661 / 663, 0 gaps), and 100 % sequence identity of LSU to Trimmatostroma salicis CPC 13571. In the multilocus phylogenetic tree (FIGURE 2), isolate UESTCC 24.0128 cluster with T. salicis MFLU 18 - 0702 formed a strongly supported clade. Morphologically, the newly collected specimen resembles the generic type, Trimmatostroma salicis, in having much more compact and well-delimited sporodochia, up to 13 - septate conidia and being non-lichenicolous (Ellis 1971, Crous et al. 2007). Therefore, we identified the newly collected specimen (HUEST 24.0139) as T. salicis, marking its first recorded occurrence in China.	en	Chen, Yanpeng, Liao, Yuechi, Shami, Ashwag, Alharbi, Nada K., Liu, Jian-Kui, Maharachchikumbura, Sajeewa S.
