On Dracaena fragrans leaves, Sexual morph: Undetermined. Asexual morph: See Manamgoda  et al. 2012 conidiophores (90–)110–234(–275) × 6–8 μm (av. = 172 SD = 62 n = 10; av. = 7, SD = 1, n = 10), arising occasionally singly or usually in groups, branched, septate, geniculate at upper part, brown to pale reddish, lighter towards apex. Conidiogenous nodes dark brown, smooth. Conidia (33–)35–57(–69) × 9–15 μm (av. = 46 SD = 11 n = 32; av. = 12 SD = 3 n = 32), smooth-walled, straight or curved, subcylindrical to fusoid, sometimes narrowly clavate, tapering towards rounded apex, basal cell obconic, pale brown to mid reddish brown , 3–4- distoseptate (av. = 4). Hilum inconspicuous, germination bipolar.

Cultural characters – Colonies growing on PDA  4–6 cm diam after 8 d incubation at 25 °C, circular with filiform margin, brown, aerial mycelium sparse to moderate, floccose with age.

Material examined – Thailand, Kanchanaburi Province, Umpang distric, on dead leaves of Dracaena sp., 24 October 2018, Napalai Chaiwan, KAN20 (MFLUCC T20-1612).

HostDracaena fragrans (This study).

Distribution – USA, Florida, from human lung biopsy specimen, 1975, (Manamgoda et al. 2012).

GenBank accession numbers – MFLU **; ITS: ***; GAPDH: waiting; TEF1: ***

Notes – See Manamgoda  et al. 2012. In this study an isolate (KAN20) of C. lunata from Thailand from an Dracaena fragrans plant substrate in 2018. This culture is sporulation.
