In September 2009, teak plants showing wilt symptoms were found in Cáceres, Mato Grosso, Brazil. Stem fragments with characteristic symptoms were collected and placed on carrot baits. After 10 days, the isolate produced black, globose (233.12 × 277.74 µm) perithecia and a long rostrum (729 µ). Ascospores had dimensions of 3.62 × 4.68 µm. Chlamydospores (10.76 × 14.03 µm) and cylindrical endoconidia (19.89 × 3.12 µm) were observed. The morphological characteristics indicated that the isolate belonged to C. fimbriata. The ITS1 and ITS4 sequenced region of the isolate (JQ354938) showed 98% similarity to the isolate of C. fimbriata strain CMW5312 (AF395687.1). This is thought to be the first report of C. fimbriata in teak in Mato Grosso.
