英文摘要：

During the investigation of nematodeLtrapping fungi in Guangxi of China, Monacrosporium megalosporum was encountered in China firstly. Its morphological character is that conidiophores are simple or occasionally branched, bearing a single conidium on the tip. Conidia are broadly fusoid-shaped, rounded at the distal end and truncate at the proximal end, with 2-4 and mainly 3 septa, trapping nematodes by means of adhesive net.
