03BC85060C37280AFC907A0FF20A9BC2.taxon	description	DESCRIPTION Saprobic on submerged decaying wood in a freshwater habitat. Sexual morph: Undetermined. Asexual morph: Colonies superficial, effuse, dark brown. Mycelium immersed, composed of pale to dark brown hyphae. Setae 81 - 135 × 4 - 5 µm (x ̄ = 103 × 4 µm, n = 15), arising from the bulbous base, often with 1 - 2 at the side of conidiophores, capitate, 2 - 3 - septate, brown, slightly constricted at some septa. Conidiophores 131 - 278 µm long, stipes 9 - 11 µm wide below venter and 9 - 15 µm wide above, 13 - 20 µm wide at the venter, macronematous, mononematous, erect, straight or slightly flexuous, solitary or 2 - 3 group, smooth-walled, dark brown to black, cylindrical, a cylindrical stipe and a swollen venter with a long cylindrical neck. Conidiogenous cells monophialidic, integrated, terminal, determinate, dark brown, lageniform, with a tubular collarette and swollen venter, flared margin at free end. Conidia 28 - 34 × 7 - 10 µm (x ̄ = 30 × 9 µm, n = 20), catenate, emerging in a chain inside the tubular collarette, develop basipetally, cylindrical, truncate at both ends, 5 - septate, with conspicuously darkened septa, hyaline when young, brown to dark brown when mature, with pale brown to subhyaline end cells.	en	Xu, Rong-Ju, Zhou, De-Qun, Yang, Zhu-Liang, Li, Ying, Zhao, Qi (2024): Two new freshwater hyphomycetous species of Sporoschisma Berk. & Broome (Chaetosphaeriales) from Tibetan Plateau, China.

03BC85060C37280AFC907A0FF20A9BC2.taxon	discussion	NOTES Morphologically, Sporoschisma lignicola R. J. Xu & Q. Zhao, sp. nov. is highly similar to S. atroviride J. Yang, J. K. Liu & K. D. Hyde, S. longicatenatum, and S. nigroseptatum in having capitate setae scattered or in groups among conidiophores, cylindrical conidiophores and catenate, cylindrical, septa, with hyaline end cells conidia (Goh et al. 1997; Yang et al. 2016, 2023). However, S. lignicola R. J. Xu & Q. Zhao, sp. nov. differs from S. atroviride in having shorter conidiophores (131 - 278 vs 275 - 390 µm) and smaller conidia (28 - 34 × 7 - 10 vs 36 - 49 (- 53) × (13 -) 14 - 15.5 (- 16) µm) (Yang et al. 2023). Sporoschisma lignicola R. J. Xu & Q. Zhao, sp. nov. differs from S. longicatenatum in having smaller sized conidia (28 - 34 × 7 - 10 vs 35 - 45.5 × 9 - 11 µm) and cylindrical, brown conidia (Yang et al. 2016). Sporoschisma nigroseptatum differs from S. lignicola R. J. Xu & Q. Zhao, sp. nov. in having longer conidiophores (300 - 410 vs 131 - 278 µm) and doliiform conidia (Goh et al. 1997). Phylogenetic analysis showed that Sporoschisma lignicola R. J. Xu & Q. Zhao, sp. nov. is located in a distinct clade within Sporoschisma, and formed a sister lineage with S. taitense with 89 % ML / 1.00 PP support (Fig. 1). However, comparison of the ITS gene region between the ex-holotype of Sporoschisma lignicola R. J. Xu & Q. Zhao, sp. nov. (KUNCC 10403) and S. taitense (KUMCC 15 - 0241) revealed a 2.1 % (11 / 536 bp, excluding gap) difference (Jeewon & Hyde 2016; Luo et al. 2016). In addition, S. lignicola R. J. Xu & Q. Zhao, sp. nov. is distinguished from S. taitense by having shorter setae (81 - 135 vs 192 - 204 µm), shorter conidiophores (131 - 278 vs 299 - 322 µm), and cylindrical to doliiform conidia (Luo et al. 2016).	en	Xu, Rong-Ju, Zhou, De-Qun, Yang, Zhu-Liang, Li, Ying, Zhao, Qi (2024): Two new freshwater hyphomycetous species of Sporoschisma Berk. & Broome (Chaetosphaeriales) from Tibetan Plateau, China.
