7F555DA3023B5642BD3CD56CA69F9FEB.taxon	description	Description. Saprobic on decaying wood submerged in a freshwater stream. Asexual morph: Colonies superficial, effuse, hairy, brown to black, scattered, with glistening conidial masses at apex. Mycelium partly superficial, partly immersed, consisting of branched, septate, smooth, smooth-walled, hyaline to pale brown hyphae. Conidiophores macronematous, mononematous, solitary, erect, unbranched, multi-septate, straight, or flexuous, cylindrical, slightly constricted at septa, 146 – 364 × 4.5 – 8 μm x ̄ = 224 × 5.8 μm, n = 25), dark brown, becoming pale brown to brown towards the apex. Conidiogenous cells polyblastic, integrated, terminal or intercalary, sympodial proliferations, sometimes denticles, cylindrical, reniform, curved, and swollen at the apex, 8.5 – 28 × 4 – 6 μm x ̄ = 20 × 5.2 μm, n = 25), pale brown to brown. Conidia acrogenous, subglobose to globose, ovoid to obovoid, or ellipsoidal, aseptate, occasionally forming chains in water, guttulate, 7.5 – 12.5 × 5 – 8.5 μm x ̄ = 8.9 × 7 μm, n = 25), light brown or black, smooth-walled, sometimes have small apiculus at the base. Sexual morph: Undetermined.	en	Zhang, Wang-ming, Song, Xiao-yu, Xie, Wan-qing, Zhou, Xin-zhong, Lu, Juan, Feng, Qin-ying (2025): Morphological and multi-gene phylogenetic analyses reveal Nigrellomyces gen. nov. and one new species in Pleurotheciaceae from China.

7F555DA3023B5642BD3CD56CA69F9FEB.taxon	description	Culture characteristics. Conidia germinate on PDA within 17 hours, producing germ tubes from the conidial body. Colonies on PDA are irregular with a flat surface and undulate margin, reaching 38 cm in diameter after 41 days at room temperature (approximately 25 ° C), and are brown to dark brown on both the surface and reverse sides.	en	Zhang, Wang-ming, Song, Xiao-yu, Xie, Wan-qing, Zhou, Xin-zhong, Lu, Juan, Feng, Qin-ying (2025): Morphological and multi-gene phylogenetic analyses reveal Nigrellomyces gen. nov. and one new species in Pleurotheciaceae from China.
