Su & Cheew sp. nov. Index Fungorum number: IF554445; Facesoffungi number : FoF 04477, Fig.6 Etymology:—In reference to China , where the holotype was collected. Holotype :— MFLU 17–1964 . Saprobic on submerged decayed wood in aquatic habitats. Sexual morph : Undetermined. Asexual morph: Hyphomycetous. Colonies on natural substratum partly superficial, effuse, scattered, hairy, velvety. Mycelium immersed, composed of septate, unbranched, subhyaline to pale brown, smooth-walled hyphae. Conidiophores (166–) 217–301 μm long ( x = 259 μm, SD = 42, n = 10), 8–10 μm wide ( x = 9 μm, SD = 1, n = 10), mononematous, macronematous, straight or slightly flexuous, unbranch, 5–7-septate, dark brown, smooth, constricted at septum. Conidiogenous cells phialidic, ampulliform, terminal, integrated, percurrent, smooth. Conidia 17–23 μm long ( x = 20 μm, SD = 3, n = 30), 5–7 μm wide ( x = 6 μm, SD = 1, n = 30), cylindrical, elongated, round at both end, slightly tapering and curved at base, 0–2-septate, hyaline, smooth. Material examined : CHINA , Yunnan Province , Dali, saprobic on decaying wood submerged in a stream in Cangshan Mountain, June 2014 , S.S.N. Maharachchikumbura, HD 3–5–3, (S-446), (MFLU 17–1964, holotype ), ex-type living culture MFLUCC 16–0965. Notes : Morphology of K. chinensis comparable to those of K. triseptata and K. peruamazonensis . However, the funnel-shaped collarette at the apex of the phialide terminates of K. chinensis and K. peruamazonensis clearly distinct from K. triseptata where it lacks a collarette ( Réblová et al. 2011 ). Kylindria chinensis can be distinguished from K. peruamazonensis by its cylindrical, slightly longer conidia. Furthermore, the septation of conidia of K. chinensis are commonly visible only during germination and in the phylogenetic analysis ( Fig. 1 , 2 ) K. chinensis formed a distinct lineage apart from K. peruamazonensis .
