Neohelicosporium hyalosporum Y.Z. Lu, J.C. Kang & K.D. Hyde

Index Fungorum number: IF 822059; Facesoffungi number: FoF 03574

Holotype: GZAAS 16-0088.

Etymology: ‘hyalo-’ referring to hyaline conidia.

 

Saprobic on submerged decaying wood. Sexual morph: undetermined. Asexual morph: hyphomycetous, helicosporous. Colonies on the substratum superficial, effuse, gregarious, white. Mycelium composed of partly immersed, partly superficial, hyaline to pale brown, septate, abundantly branched hyphae, with masses of crowded, glistening conidia. Conidiophores up to 540 μm long, 4–5.5 μm wide, micronematous, mononematous, flexuous, long, cylindrical, branched, septate, smooth-walled. Conidiogenous cells 9–13 μm long, 4–5.5 μm wide, holoblastic, mono- to polyblastic, integrated, intercalary, cylindrical, with denticles, pale brown, smooth-walled. Conidia 25–33 μm diam. and conidial filament 3–4 μm wide (x̄ = 28 μm diam., 3.5 μm wide, n = 50), 125–225 μm long, tightly coiled 2.5–3.5 times, becoming loosely coiled in water, rounded at the tip, multi-septate, guttulate, hyaline.
