Liu, Z.Q. Zeng & W.Y. Zhuang , sp. nov. FIGURE 2 Fungal Names: FN570867 Etymology:—Referring to the large-sized macroconidia produced by the fungus. Typification :— China , Chongqing City , Wushan County , Hongchiba National Forest Park , 31°54′52′′ N , 109°08′56′′ E , in soil, 30 October 2020 , Z.Q. Zeng , X.C. Wang , H.D. Zheng & C. Liu , CS25-8 ( CGMCC 3.20680 ) . Description: —Colonies on PDA reaching 36−39 mm diam. after 2 wk at 25 °C, slimy appearance due to abundant sporulation on medium surface, orange to pale yellow in center, pinkish orange at margin. Colonies on MEA reaching 35−39 mm diam. after 2 wk at 25 °C, surface floccose, with white aerial mycelium, light cinnamon in center. Colonies on SNA reaching 36−38 mm diam. after 2 wk at 25 °C, aerial mycelium absent, sporulation on center medium surface, light yellow to white. Colonies on OA reaching 39−40 mm diam. after 2 wk at 25 °C, aerial mycelium absent with slimy appearance due to abundant sporulation on medium surface, light yellow. FIGURE 1. BI tree generated based on the combined dataset of ITS and LSU sequences of Fusicolla species. Supporting values showing at branches: BIPP (left) and MLBP (right). Asexual stage fusarium-like. Conidiophores arising directly from somatic hyphae, simple or rarely branched, monochasial, straight, hyaline, smooth-walled, aseptate or with basal septum, up to 42 µm long. Conidiogenous cells monophialidic or rarely polyphialidic, arising laterally from hyphae or in terminal pairs, cylindrical to subulate, 8−14 × 1.5−3 µm, thin- and smooth-walled. On PDA, macroconidia falcate, long fusiform, slightly narrowing towards the ends, acute, the apical cell often hooked with a more or less pointed tip, basal cell slightly pedicellate, hyaline, thin-and smooth-walled, (1−)3(−4)-septate, (25−)36−42(−53) × 2.5−3.5 µm (av. 39.5 × 2.8 µm) (n = 30), microconidia slightly curved to C-shaped, hyaline, smooth, aseptate, 11–18(−22) × 0.85–1.3 µm (av. 15.7 × 1.1 µm) (n = 20). On OA, macroconidia falcate, generally crescent to threadlike, (3–)4–9-septate, (32−)40–65(−80) × 2.3–3.8 µm (av. 53.2 × 2.9 µm) (n = 30), microconidia strongly curved, hyaline, smooth, 0−4(−5)-septate, (12−)15–24(−32) × 0.85–1.4(−2.2) µm (av. 19.3 × 1.2 µm) (n = 30). Sexual stage not observed.
