Index Fungorum number: IF553862; Facesoffungi number: FoF03768
Etymology: The name lignicola is derived from the words “lignum”, meaning wood and cola, meaning habitat, referring to the habitat in which this fungus was found
Holotype: MFLU 17–1422
Saprobic on submerged decayed wood in aquatic habitats. Sexual morph: Undetermined. Asexual morph: Hyphomycetous. Conidiomata on natural substratum sporodochia, 200 μm to 1 mm diam., superficial, compact, scattered, circular or subglobose, dark brown to black, velvety. Mycelium immersed, consisted of septate, branched, smooth, thin-walled, hyaline, 2–4 μm wide hyphae. Conidiophores micronematous, reduced, pale brown, smooth. Conidiogenous cells holoblastic. Conidia appearing broadly rounded in upper half, composed of uniformly medium brown, compactly adpressed 4–6 apically curved rows of cells appearing muriform, cheiroid, 46–54 μm long (x̄ = 50 μm, SD = 4, n = 40), 21–27 μm wide, (x̄ = 24 μm, SD = 3, n = 40); in lower half with a broadly ovate to subglobose, hyaline, smooth basal cell, 16–22 μm long (x̄ = 19 μm, SD = 3, n = 40), 12–15 μm wide, (x̄ = 13.5 μm, SD = 1.5, n = 40), not complanate, secession schizolytic. Conidial appendages absent
Specimen examined: CHINA, Yunnan Province, saprobic on decaying wood submerged in a stream in Cangshan Mountain.
