Collection of samples, isolation and characterisation

Submerged dicotyledonous leaves were collected from a stream in Hainan. Samples were collected in zip-lock plastic bags and labelled and then transported to the laboratory. The rotten leaves were cut into several 2–4 × 2–4 cm sized fragments in the laboratory and then spread on to the surface of CMA (20 g cornmeal, 18 g agar, 40 mg streptomycin, 30 mg ampicillin, 1000 ml distilled water) medium for 10 days; a single conidium was isolated and cultivated on CMA in Petri plates using sterilised needles while viewing with a BX51 microscope. Morphological observations were then made from CMA after incubation at 28 °C for one week. Measurement data were based on 30 random conidia and 10 conidiophores. Pure cultures were deposited in the Herbarium of the Laboratory for Conservation and Utilization of Bio-Resources, Yunnan University, Kunming, Yunnan, P.R. China (YMF, formerly Key Laboratory of Industrial Microbiology and Fermentation Technology of Yunnan) and at the China General Microbiological Culture Collection Center (CGMCC).
