Colletotrichum jiangxiense F. Liu and L. Cai, Persoonia 35: 82 (2015) (Figure 7)

Index Fungorum number: 809161

Saprobic or pathogenic on dead Asian House Gecko, white, cottony mycelium on the skin. Sexual morph: undetermined. Asexual morph: Mycelium 1.5–3.5 μm wide (x̅ = 2.5 μm, n = 30), granular to smooth, branched, with thick-walled septa. Conidiophores 2.5–5 μm (x̅ = 4 μm, n = 15), straight to slight curved, septate, smooth-walled, narrow in the terminal with a hyaline, cylindrical. Conidiogenous cells 10–20 × 1–3 µm (x̅ = 13 × 2.5 μm, n = 20), cylindric to flask-shaped, tapering at apex to narrow, phialidic conidiogenous locus. Conidia 10–20 × 3–5 μm (x̅ = 14 × 4 μm, n = 20), cylindrical to oblong, hyaline, thick-walled, granular to smooth, around, both ends bluntly rounded, or some see bottom end acute, appressoria not observed.

Substratum: Camellia sinensis (Liu et al. 2015, Jayawardena et al. 2016 a, Wang et al. 2020); Citrus sinensis (De Silva et al. 2017) Persea americana (Fuentes-Aragón et al. 2020);

Distribution: China (Liu et al. 2015, Jayawardena et al. 2016 a, De Silva et al. 2017, Wang et al. 2020); Mexico (Fuentes-Aragón et al. 2020);

Material examined: China, Yunnan Province, on dead Asian House Gecko, Peter E. Mortimer, F-1 (Herb. KUN-HKAS 122653), living culture, KUMCC 21-0466. Genbank numbers: ITS: OM 670162, HIS: OM 744410, CAL: OM 744409, ACT: OM 744408, tub2: OM 744407, GPDH: OM 744411.

Culture characteristics: Colonies on PDA fast-growing, reach 60 mm in one week, above effuse, aerial mycelium, cottony, light grayish to olivaceous with white margin. Reverse: grayish orange to pale brown, black-brown at the central inoculation, with black pigmented margin, not sporulated, without pigments produced in PDA.

Notes: Colletotrichum jiangxiense was first introduced by Liu et al. (2015) from Jiangxi province, China. Our isolate KUMCC 21-0466 has similar morphologies to members of Colletotrichum, and the BLASTn results of GAPDH, CHS- 1, ACT, tub2, CAL and ITS of our strain indicate 99–100% similarity with C. jiangxiense ZY 12 and C. jiangxiense (COP 27.905, LF 488). The multi-locus phylogenetic trees also showed our new isolate clusters together with C. jiangxiense ZY 12 with high statistical support values (ML: 94%, BI: 0.96; Figure 6); thus, we report C. jiangxiense KUMCC 21-0466 as a new host record associated with a reptile (Asian House Gecko) in this study.
