Colonies on natural substrate superficial, white, effuse, gregarious, with massive glistening conidia. Mycelium partly superficial, composed of hyaline to pale brown, branched, septate, guttulate, smooth hyphae. Conidiophores 144 – 193.5 × 3.5 – 6.5 μm (x – ̄ = 167.5 × 5 μm, n = 25), macronematous, mononematous, erect, cylindrical, straight or slightly flexuous, typically curved at the apex, unbranched, septate, subhyaline to pale brown, thick-walled. Conidiogenous cells 11.5 – 15 × 3.5 – 5 μm (x – ̄ = 13.5 × 4 μm, n = 30), holoblastic, monoblastic, or polyblastic, integrated, intercalary, cylindrical, with denticles, subhyaline to pale brown, smooth-walled. Conidia solitary, pleurogenous, helicoid, tapering towards the rounded ends, developing on tooth-like protrusions, 14.5 – 17 μm diam., and conidial filament 2 – 4 μm wide (x – ̄ = 15.5 × 3 μm, n = 25), 82.5 – 126.5 μm long (x – ̄ = 105.5 μm, n = 30), tightly coiled up to 3 1 / 2 times, becoming loosely coiled in water, aseptate, guttulate, hyaline, smooth-walled.	en	Ma, Xiao-Yan, Song, Dan-Dan, Ma, Jian (2025): Morphological and phylogenetic analyses reveal two new species of Neohelicomyces (Tubeufiales, Tubeufiaceae) from China.

6CA725B7D38A56949E7F411C2D3CC073.taxon	description	Culture characteristics. Conidia germinate on PDA within 10 hours, producing germ tubes from the conidial body. Colonies on PDA are circular with a raised surface and entire margin, reaching 5 cm in diameter after 45 days at room temperature (approximately 25 ° C), and are pale brown to dark brown on both the surface and reverse sides.	en	Ma, Xiao-Yan, Song, Dan-Dan, Ma, Jian (2025): Morphological and phylogenetic analyses reveal two new species of Neohelicomyces (Tubeufiales, Tubeufiaceae) from China.
