Ochroconis musae

Ochroconis musae (G.Y. Sun & Lu Hao) Samerp. & de Hoog, Mycological Progress 14 (2/6): 8 (2015)

Facesoffungi number: FoF06957


Saprobic on Draceana. Sexual morph: Undetermined. Asexual morph: Full descriptions of this species were given by Hao et al. )2013( and by Samerpitak et al. )2015( under its synonymous name O. mirabilis. Conidiophores mostly arising laterally from vegetative hyphae, erect or flexuous, cylindrical with 1–2 septa, at 25°C. Conidia were T or Y shaped or bilobed, cylindrical, ellipsoid, clavate or fusiform.


Culture characteristics:  Conidia germinated on PDA within 24 hours with germ tubes produced from one or both end cells, mostly from basal cell of conidia. Colonies on PDA reaching 25–30 mm in diameter after 2 weeks at 25–30°C, colonies circular, flat, moderately expanding, smooth, dry, greyish brown to dark brown, submerged colony margin, reverse as dark brown in the central portion; not producing pigmentation in agar. Mycelium hyphae subhyaline to pale brown, smooth- and thick-walled.


Material examined: THAILAND, Chiangmai Province, on dead leave of Draceana, 27 September 2017, Napalai Chaiwan, NCCM003 living culture, MFLUCC 17–2598 (new host record).


GenBank numbers: ITS: MN788641, LSU: MN788642


Notes: Our strain shares similar morphological characters with O. musae which was isolated from banana, Musa basjoo, in Ledong county, Haikou City, Hainan Province, China (Samerpitak et al. 2015). The phylogenetic analysis also supports a close relatedness to O. musae. The mycelium of Ochroconis consists of smooth, pale brown to medium brown. However, previously O. musae has only been reported from banana. This study provides the first report of new host record of this species from Dracaena as well as its first report from Thailand.
