Neotorula submersa

Neotorula submersa Z.L. Luo, H.Y. Su & K.D. Hyde

Index Fungorum number: IF 552138; Facesoffungi number: FoF 02217

Holotype: HKAS 92660

Etymology: With reference to the submerged habitat.

 

Saprobic on submerged decaying wood. Sexual morph Undetermined. Asexual morph Colonies on the substrate superficial, effuse, gregarious, hairy, dark brown. Mycelium immersed, composed of septate, branched, thin-walled, smooth, pale brown hyphae. Conidiophores mononematous, macronematous, branched or unbranched, septate, erect, straight or flexuous, smooth, pale brown, cylindrical, 2–5-septate, 18–48 μm (x̄ = 33 μm, SD = 15, n = 10) long, 4–5 μm (x̄ = 4.5 μm, SD = 0.5, n = 10) wide. Conidiogenous cells mono- to polytretic, integrated or discrete, terminal, pale brown, doliiform or lageniform. Conidia acrogenous, in short chains, dry, clavate to subcylindrical, rounded at the apex, 2–4-septate, dark bands at the septa, verruculose, pale yellow when young, tawny to brown when mature, 16–22 μm (x̄ = 19 μm, SD = 3, n = 25) long, 5–6 μm (x̄ = 5.5 μm, SD = 0.5, n = 25) wide. Conidial secession schizolytic. (Descriptions from Hyde et al. 2016)

 

Material examined: CHINA, Yunnan Province, saprobic on decaying wood submerged in Dulong River, May 2015, X.C. Tao, HD 1–10–7 (HKAS 92660, holotype), ex-type culture, KUMCC 15-0280, MFLUCC.

 

Notes: Neotorula submersa was collected from north-western Yunnan Province. It differs from N. aquatica in having thinner conidiophores (4–5 μm vs. 6–7 μm) and longer conidia (16–22 μm vs. 11–16 μm). The conidia of N. aquatica are pale green when young and brown when mature, in N. submersa they are pale yellow when young and tawny to brown when mature. Phylogenies also reveal a close relationship between these two taxa (Notes from Hyde et al. 2016)

 

Freshwater distribution: China (Hyde et al. 2016)
