AE1AA39F98DC5F1398F9269F9A89305C.taxon	description	Description. Saprobic on decaying wood in a terrestrial habitat. Sexual morph Undetermined. Asexual morph Hyphomycetous. Colonies on the natural substrate effuse, hairy, brown, with white, glistening conidial mass. Mycelium mostly immersed, composed of branched, septate, smooth, brown hyphae. Setae 170 – 251 µm long, 5 – 7 µm wide at the base (x ̄ = 210 × 6 µm, n = 15), erect, slightly curved, dark brown at the base, pale brown towards the apex, apical cell with a round end, septate, unbranched, smooth. Conidiophores 63 – 251 µm long, 4 – 7 µm wide at the base (x ̄ = 122 × 5.5 µm, n = 15), macronematous, mononematous, brown at the base, fading to pale brown towards the apex, septate, unbranched, cylindrical, erect, straight or slightly curved, thin-walled, smooth, arising in groups from the bases of setae. Conidiogenous cells 19 – 30.5 µm long, 3.5 – 5 µm wide (x ̄ = 23.5 × 4.5 µm, n = 25), mono- or poly-phialidic integrated, terminal, determinate, clavate, ellipsoidal, collarette funnel-shaped. Conidia 10 – 16 µm long, 2 – 3.5 µm wide (x ̄ = 14.5 × 3 µm, n = 20), acrogenous, usually aggregated in slimy droplets, hyaline, 1 - septate, guttules, oblong to allantoid, slightly curved, rounded at ends, smooth, with 5 – 12.5 μm long hair – like appendages at both ends.	en	Zhang, Wangming, Feng, Qinying, Song, Xiaoyu, Zhou, Xinzhong, Xie, Wanqing, Lu, Juan, Lu, Li (2025): Two new species of Stilbochaeta (Chaetosphaeriaceae, Chaetosphaeriales) from freshwater and terrestrial habitats in China.
