Subuliphorum cylindrosporum Y. Wang & H. Chen sp. nov. Fig. 4 Etymology. The name refers to the cylindrical conidia, a distinctive morphological feature of this species. Type. China, • Guizhou Province, Guian New District (26°23'52"N, 106°27'10"E, alt. 1230 m), isolated from the rhizosphere soil of Gaultheria leucocarpa var. yunnanensis, May 2025, Yao Wang (holotype a dried culture GMB 3012); ex-type living culture GMBC 3012. Description. Colonies on PDA 27–30 mm diam after 14 d at 25 ° C, flat, felty at center, creamy white; reverse luteous with a buff margin. Mycelium consisting of branched, septate, hyaline, smooth- and thin-walled hyphae, 1.5–2.5 μm wide. Conidiophores aggregated or solitary, erect, straight to curved, arising from aerial or submerged hyphae or from mycelial ropes, unbranched or basitonously branched, bearing 1–3 whorls of 1–3 phialides; sporodochia formed in older cultures; branching pattern verticillate; conidiophores 15–45 × 1–2 μm (x ̄ = 28 × 1.5, n = 50), with 1–2 septa, hyaline, smooth-walled, walls thicker than those of vegetative hyphae. Phialides lateral or terminal, arising laterally from hyphae or formed in small monopodial clusters on conidiophores; subulate, hyaline, thin- and smooth-walled, 14.0–25.5 μm long, 0.9–2.1 μm wide at base (x ̄ = 20 × 1.6, n = 50); collarette inconspicuous; polyphialides not observed. Conidia aseptate, cylindrical, hyaline, thin- and smooth-walled, 3.2–4.8 × 1.5–2.0 μm (x ̄ = 3.8 × 1.7, n = 50), aggregated in slimy...
