Sexual morph: undetermined. Asexual morph: hyphomycetous. Colonies on the substratum superficial, effuse, gregarious, white. Mycelium composed of partly immersed, partly superficial, hyaline, septate, branched hyphae. Conidiophores 17–24 × 4–5 μm (x ̄ = 19 × 4.5 μm, n = 20), macronematous, mononematous, solitary, erect, unbranched, subcylindrical, flexuous, hyaline, 0–1 - septate. Conidiogenous cells 8.5–11 × 3.5–4.5 μm (x ̄ = 10 × 4 μm, n = 20), holoblastic, polyblastic, integrated, terminal, sympodial, irregular subcylindrical, flexuous, hyaline, apical part forming a rachis with numerous, aggregated, cylindrical denticles. Conidia 19–34 × 3.5–5 μm (x ̄ = 30 × 5 μm, n = 35), solitary, acropleurogenous, 0–3 - septate, mostly 3 - septate, cylindrical, fusiform to obclavate, subobtuse at apex, hyaline, smooth, prominently guttulate.</p><p>Culture characteristics.</p><p>Conidia germinate on PDA within 11 hours, producing germ tubes from the conidial body. Colonies on PDA are irregular, with a flat to slightly raised surface and an entire margin, reaching 31 cm in diameter after 36 days at room temperature (approximately 25 ° C). Surface light brown to dark brown, with the point of attachment dark brown to nearly black, exhibiting radiating pigmentation; reverse pale yellow to grayish yellow, with a slightly darker center showing olivaceous to gray-green tinges; margin lighter, appearing pale yellow to whitish.</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; Zhongzhe Li, GZAAS 25-0785, holotype, ex-type living culture GZCC 27-27594 ; • ibid., GZAAS GZAAS 25-0786, isotype, ex-isotype culture GZCC 27-27595 .</p><p>Notes.</p><p>In the phylogenetic tree (Fig. 1), the isolates GZCC 27-27594 and GZCC 27-27595 form a sister clade to Phragmocephala stemphylioides (KAS 4277) with strong support (100 % ML, 1.00 PP). However, pairwise sequence comparisons between Dentisympodium fusiforme (GZCC 27-27594) and P. stemphylioides reveal 56 / 536 bp differences in ITS (10.5 %, including 20 gaps) and 17 / 842 bp differences in LSU (2.0 %, excluding gaps). Morphologically, D. fusiforme is clearly distinguishable from P. stemphylioides by its hyaline conidiophores; sympodial, irregularly subcylindrical, hyaline conidiogenous cells bearing denticles; and cylindrical, fusiform to obclavate, hyaline conidia. In contrast, P. stemphylioides possesses pale brown to brown conidiophores, subhyaline to pale brown, cylindrical conidiogenous cells, and obovoid, dematiaceous conidia (Hughes 1958; Réblová et al. 2016; Bao et al. 2022). Therefore, based on multigene phylogenetic evidence together with distinct morphological differences, we introduce a new genus, Dentisympodium, to accommodate D. fusiforme as a novel species.</p></div>	https://treatment.plazi.org/id/CDCC115B346C505C8FDA27B70063E80F	Public Domain	No known copyright restrictions apply.

Phylogenetically, Dentisympodium forms a distinct clade within Pleurotheciaceae, supporting its recognition as a novel genus. Accordingly, we introduce Dentisympodium to accommodate a new species, D. fusiforme, which is designated as the type species based on both molecular evidence and its distinctive conidial morphology.</p></div>	https://treatment.plazi.org/id/7C1CA3014B0B593FBB5B9E1302AB518F	Public Domain	No known copyright restrictions apply.
