Colonies on natural substrate superficial, effuse, gregarious, with masses of crowded, glistening conidia, white to brown. Mycelium partly immersed, partly superficial, composed of hyaline to pale brown, branched, septate, smooth hyphae. Conidiophores 106 – 212 × 3 – 4.5 μm (x ̄ = 176 × 4 μm, n = 25), macronematous, mononematous, erect, cylindrical, flexuous, widest at the base, tapering towards narrow apex, branched or unbranched, septate, brown at base, subhyaline towards apex, thick-walled. Conidiogenous cells 7.5 – 25 × 2 – 4 μm (x ̄ = 13.5 × 3.5 μm, n = 25), holoblastic, monoblastic, or polyblastic, integrated, terminal or intercalary, cylindrical, with denticles, subhyaline to pale brown, smooth-walled. Conidia solitary, acropleurogenous, helicoid, developing on tooth-like protrusion, 15 – 21 μm diam. and conidial filament 2.5 – 3.5 μm wide (x ̄ = 17.5 × 3 μm, n = 20), 107 – 143 μm long (x ̄ = 128.5 μm, n = 30), loosely coiled 2 1 / 2 – 3 times, becoming loosely coiled in water, septate, guttulate, hyaline, smooth-walled.	en	Gao, Fan, Tan, Ting-Hong, Bai, Song, Wu, Chun-Fang, Zhao, Ning-Ning, Qiu, Na, Zhou, Min, Ma, Jian (2025): Two new species of Neohelicomyces (Tubeufiaceae, Tubeufiales) from Hainan Province, China.

609D76864B515D7B941966681785D632.taxon	description	Culture characteristics. Conidia germinated on PDA and produced germ tubes within 11 h. Colonies on PDA reached 27 mm in diameter after 40 days of incubation at 25 ° C, with an irregular shape, raised surface, and undulate margin, pale brown to brown; the reverse was brown to dark brown.	en	Gao, Fan, Tan, Ting-Hong, Bai, Song, Wu, Chun-Fang, Zhao, Ning-Ning, Qiu, Na, Zhou, Min, Ma, Jian (2025): Two new species of Neohelicomyces (Tubeufiaceae, Tubeufiales) from Hainan Province, China.
