F042879013272B24FD8E700FD4B9FEF2.taxon	etymology	Etymology: The epithet “ yadongensis ” refers to the collecting site where the fungus was collected. Holotype: HKAS 134926 Saprobic on dead wood in terrestrial habitat. Sexual morph: Undetermined. Asexual morph: Hyphomycetous. Colonies effuse on natural substrate, dark brown to black. Mycelium immersed, septate, branched, brown hyphae. Conidiophores macronematous, erect, straight or slightly curved, synnematous, dark brown to black, cylindrical, septate. Synnemata erect, dark brown, composed of parallel and adpressed conidiophores, smooth, 1230 – 1440 µm (x ̅ = 1342.7 µm, n = 10) long, 250 – 310 µm (x ̅ = 290.6 µm, n = 10) wide at the base, 50 – 150 µm (x ̅ = 95.1 µm, n = 10) wide in the middle, 310 – 405 µm (x ̅ = 359.7 µm, n = 10) wide at the apical region. Conidiogenous cells clavate to oblong, brown to dark brown, monotretic, terminal, integrated, smooth, 6.5 – 10.5 × 4.5 – 6 µm (x ̅ = 8.4 × 5.3 µm, n = 20). Conidia brown, rounded at the ends, smooth, clavate, straight or lightly curved, mostly 1 - septate at the middle, rarely 2 - septate, not or constricted at septa, septa darker than the rest of the cell, normally guttulate, 21.5 – 26.5 × 4.5 – 6 µm (x ̅ = 23.9 × 5.3 µm, n = 30). Culture characteristics: Conidia germinate on PDA within 24 h at 15 – 20 ºC in a natural light. Germ tubes are produced from one end. Colonies reach 3.55 cm diam after one month at 20 ºC, circular, cottony surface, flat, entire edge, dense hyphae, light pink in the center, white around from above, yellow-brown around, brown in the center from below, no pigment.	en	Wang, Zhi-Yang, Thiyagaraja, Vinodhini, Maharachchikumbura, Sajeewa S.

F042879013272B24FD8E700FD4B9FEF2.taxon	materials_examined	Material examined: CHINA, Xizang Autonomous Region (Tibet), Shigatse City, Yadong County, (27 ° 13 ’ 56.65 ’ N, 89 ° 0 ’ 52.81 ’ E, 4070 m), woody litters in alpine scrub, on dead wood of unidentified host in terrestrial habitat, 25 July 2023, Shu-Cheng He, CT 15 (HKAS 134926, holotype), ex-type KUNCC 24 - 17780. ibid., CT 23 (HKAS 134927, isotype), living culture KUNCC 24 - 17781. Notes: In phylogenetic analysis, Vamsapriya yadongensis clusters with V. uniseptata, however this relationship was not statistically supported (Figure 1). The base pair comparison between Vamsapriya yadongensis (KUNCC 24 - 17780) and V. uniseptata (GZCC 21 - 0892) reveals bp differences (without including gaps) of 26 / 439 (5.92 %) and 3 / 803 (0.37 %) for the ITS and LSU region respectively. Vamsapriya yadongensis (KUNCC 24 - 17780, KUNCC 24 - 17781) closely resembles V. uniseptata, sharing similar characters such as similar shape of synnemata and conidia. However, Vamsapriya yadongensis differs from V. uniseptata in having larger conidia (21.5 – 26.5 × 4.5 – 6 µm vs. 14 – 19 × 3.5 – 4.5 µm), relatively larger synnemata (1230 – 1440 × 50 – 150 µm vs. up to 1300 × 30 – 50 µm), more than one septate per conidium (1 – 2 - septate vs. 1 - septate) and number of guttules in each cell (1 – 5 vs. 1). Therefore, Vamsapriya yadongensis is introduced as a novel species based on morphological and phylogenetic analyses following the guidelines of Maharachchimbukura et al. (2021).	en	Wang, Zhi-Yang, Thiyagaraja, Vinodhini, Maharachchikumbura, Sajeewa S. N., Dissanayake, Lakmali S., He, Shu-Cheng, Al-Otibi, Fatimah, Zhao, Qi (2024): Vamsapriya yadongensis sp. nov.
