Paraneoaraneomyces guizhouensis Y. Wang & H. Chen sp. nov. Fig. 3 Etymology. The specific epithet refers to Guizhou Province, China, where the holotype was collected. Type. China, • Guizhou Province, Guian New District (26°23'48"N, 106°27'08"E, alt. 1235 m), isolated from the rhizosphere soil of Gaultheria leucocarpa var. yunnanensis, May 2025, Yao Wang (holotype a dried culture GMB 3009); ex-type living culture GMBC 3009. Description. Colonies on PDA reaching 35–40 mm in diameter in 30 days at 25 ° C, white, slightly raised at center, plicate, nearly circular with regular margin; reverse pale yellow. Hyphae hyaline, smooth, branched, septate, 1.0–2.2 μm wide. Phialides arising from aerial or vegetative hyphae, solitary or occasionally in whorls, straight to slightly curved, tapering toward the apex, base slightly enlarged, smooth, hyaline, 28.0–69.0 × 0.8–1.9 μm (x ̄ = 56.0 × 1.3, n = 50). Conidia formed at phialide apices, often aggregated in small globose heads, cymbiform to reniform, smooth-walled, aseptate, 3.5–7.0 × 1.5–2.5 μm (x ̄ = 4.9 × 2.0, n = 50). Sexual morph not observed. Other material examined. China, • Guizhou Province, Guian New District (same locality and habitat as the holotype), May 2025, Yao Wang (living culture GMBC 3010). Substrate. Rhizosphere soil. Distribution. Known only from Guizhou Province, China. Notes. In the six-locus phylogeny (ITS, SSU, LSU, tef - 1 α, rpb 1, and rpb 2), strains GMBC 3009 (ex-type) and GMBC 3010 of Paraneoaraneomyces guizho...
