Asexual morph: Hyphomycetous. Colonies on natural substrate superficial, effuse, gregarious, with hyaline conidial masses at the apex. Mycelium partly superficial, consisting of branched, septate, smooth-walled, hyaline to pale brown hyphae. Conidiophores 163–211 × 4–6 μm (x ̄ = 183.5 × 5 μm, n = 30), macronematous, synnematous, group, cylindrical, straight or slightly flexuous, septate, subhyaline to brown, percurrently proliferating from cut ends. Conidiogenous cells 29–43 × 4–5 μm (x ̄ = 34 × 4.5 μm, n = 30), polyblastic, integrated, sympodial, cylindrical, smooth, subhyaline to pale brown. Conidia 7–19 × 3–4.5 μm (x ̄ = 10.5 × 4 μm, n = 35), acropleurogenous, ellipsoidal to oval, apically rounded, with a narrowed frill-like, 0–2 - septate, slightly constricted at the central septum, guttulate, hyaline, smooth-walled. Sexual morph: Undetermined.</p><p>Culture characteristics.</p><p>Conidia germinate on PDA within 14 h, producing germ tubes from the conidial body. Colonies on PDA are irregular, with a flat surface and an undulate margin, reaching 33 mm in diameter after 39 days at 25 ° C, and are white on both the surface and reverse.</p><p>Material examined.</p><p>China • Guizhou Province, Guiyang City, Baiyun District, Changpo Ling National Forest Park, on decaying wood in a freshwater habitat, 12 October 2025, Wang-Ming Zhang &amp; Qinying Feng, XC 6 (GZAAS 25-0787, holotype), ex-type living culture GZCC 27-27596 ; ibid., XC 7 (GZAAS 25-0788, paratype), living culture GZCC 27-27597 .</p><p>Notes.</p><p>According to a BLASTn search on NCBI GenBank, the ITS and LSU sequences of the new isolate (GZCC 27-27596) share 85.79 % similarity across 98 % of the query sequence coverage and 96.27 % similarity across 100 % of the query sequence coverage with T. obclavata (CZCC 24-0140), respectively. In addition, base-pair comparisons between H. aquaticum (GZCC 27-27596) and T. obclavata (CZCC 24-0140) show 70 / 473 bp differences in ITS (14.8 %, gaps 15 bp) and 12 / 813 bp differences in LSU (1.5 %, gap of 1 bp). Morphologically, H. aquaticum (GZAAS 25-0787) can be readily distinguished from T. obclavata (GZAAS 24-0049) by its unique conidial morphology (ellipsoidal to oval, hyaline vs. fusiform to obclavate, brown) (Liu et al. 2024).</p></div>	https://treatment.plazi.org/id/5D13FDB4A92358F09CEFE75EFC3B3238	Public Domain	No known copyright restrictions apply.

Feng .</p><p>Notes.</p><p>Hyalosympodium is proposed here to accommodate a lignicolous freshwater species collected from Guizhou Province, China. Phylogenetic analyses indicate that H. aquaticum forms a sister relationship with Tenebrosynnematica obclavata (CZCC 24-0140), with strong support (94 % ML, 1.00 PP; Fig. 1). Morphologically, Hyalosympodium is distinguished from other Pararamichloridiales species by its distinct gregarious colonies and ellipsoidal to oval conidia (Raja et al. 2003; Jaklitsch et al. 2013; Crous et al. 2015; Hernández-Restrepo et al. 2017; Liu et al. 2024; Tan and Shivas 2024; Crous et al. 2025; Tan et al. 2026). Based on these combined morphological and phylogenetic data, the new genus Hyalosympodium ( Pararamichloridiales, Diaporthomycetidae) is therefore established to accommodate H. aquaticum .</p></div>	https://treatment.plazi.org/id/4D591CDBF42352639AAEE20249131D6E	Public Domain	No known copyright restrictions apply.
