Arundinacea in vitro. After cultivation on PDA at 26℃ under continuous fluorescent light for 6 days, the colonies were black green and the hyphae were septate. Spore size was 30.6~17.0 μm×10.9~13.6 μm, mostly with four-septa. The central cell was dark and the third cell from the base was the largest. The DNA sequence of ribosomal ITS of the isolates was found to match 100% with an ITS sequence of Curvularia affinis in GenBank. This is the first report of leaf spot caused by C. affinis on F.
