Chaetomium cochliodes Palliser, North American Flora 3 (1): 61 (1910) (Figure 6)

Index Fungorum number: IF257241

Endophytic on fresh leaves of Coriaria nepalensis, sporulated after half month. Sexual morph on PDA: Ascomata 25–340 µm (x = 280 µm, n = 20) high, 140–195 µm (x = 165 µm, n = 20) superficial, ostiolate, yellowish to greenish olivaceous in reflected light because of ascomatal hairs, ellipsoid or subglobose. Ascomatal wall 3–7 µm wide, brown, membranaceous, terminal hairs verrucose, septate, dark brown, fading and tapering towards the tips. Hamathecium 3–5 µm wide, hyaline, septate, branched, cellular, embedded in a glutinous matrix, paraphyses. Asci 26–40 × 9–14 µm (x= 33 × 12 µm, n = 30), long pedicellate 20–30 µm long, with eight biseriate ascospores, evanescent, thin-walled. Ascospores 8.5–11 × 6.5–8.5 µm (x= 10 × 7.5 µm, n = 30), limoniform, verrucose, hyaline when immature, olivaceous after mature, with and apical germ pore. Asexual morph: Unknown.

Substratum: Saccharum officinarum (Teng 1996); Pinus halepensis (Botella et al. 2010); Fresh leaves of Coriaria nepalensis (this study); Unknow (Wang et al. 2022c); Panax notoginseng (Wang et al. 2016b) .

Distribution: China (Teng 1996, Wang et al. 2016b, this study), Spain (Botella et al. 2010), American (Wang et al. 2022c).

Material examined: China, Yunnan Province, Kunming, Kunyang, an abandoned and Open-Pit Phosphate Mine, on fresh leaves of Coriaria nepalensis, 22August 2022, C. J. Dao, 2 MS5 L2 (HKAS 129064), living culture KUNCC23- 13353. GenBank number: ITS: OR094463, LSU: OR094458, rpb2: OR095637, tub2: OR09563742 .

Notes: The morphological characteristics of Chaetomium cochliodes (KUNCC 23-13353) well-fits with the generic type of Chaetomium . Based on the ex-epitype of Ch. cochliodes (CBS 155.52), we conclude they have mostly similar size in asci and ascospores, and terminal hairs (Wang et al. 2016b). In addition, results from the ITS, LSU, rpb2 and tub2 nucleotide BLASTn search indicate our strain (KUNCC 23-13353) gives 99–100% similarity with Ch. cochliodes (LC 13552, LC 13504, LC13510, CBS 155.52). The phylogenetic results also match with Ch. cochliodes strains (Figure 5). Therefore, we introduce Ch. cochliodes (KUNCC 23-13353) as a new host record isolated from fresh leaves of Coriaria nepalensis .
