Fusicolla guangxiensis Z.Q. Zeng, C. Liu & W.Y. Zhuang , sp. nov. FIGURE 3

Fungal Names: FN570866

Etymology:—Referring to the type locality of the fungus.

Typification:— China, Guangxi autonomous region, Fangchenggang City, Shangsi County, Shiwandashan National Forest Park , 21°54′40′′ N, 107°55′24′′ E, on rotten twig, 10 December 2019, Z.Q. Zeng & H.D. Zheng, 12537 ( CGMCC 3.20679 ) .

Description: —Colonies on PDA reaching 20−22 mm diam. after 2 wk at 25 °C, slimy appearance due to abundant sporulation on medium surface. Orange in center, pale luteous at margin. Colonies on MEA reaching 34−37 mm diam. after 2 wk at 25 °C, slimy surface, orange to pale yellow. Colonies on SNA reaching 32−34 mm diam. after 2 wk at 25 °C, aerial mycelium rare to absent, light yellow. Colonies on OA reaching 47−50 mm diam. after 2 wk at 25 °C, aerial absent with slimy appearance due to abundant sporulation on medium surface, pale yellow to buff.

Asexual stage fusarium-like. Conidiophores arising directly from somatic hyphae, simple or rarely branched, monochasial, straight, hyaline, smooth-walled, aseptate or with basal septum. Macroconidia on PDA long-fusiform, somewhat curved falcate, acute at both ends, a few slightly hooked at both ends, hyaline, smooth, (0–)1(–3)-septate, (12–)15–29 × 1.3–2.3 µm (av. 22.13 × 1.88 µm) (n = 30). Macroconidia on OA, 0–3(–4)-septate, (12–)31–49 × 2.2–3.3 µm (av. 41.6 × 2.9 µm) (n = 30). Microconidia absent.

Sexual stage not observed.
