Abstract

In recent decades, commercial plantations have expanded toward the warm and humid regions of northern and northeastern Brazil, where leaf blight (CLB) has become the primary fungal leaf disease of this crop. CLB can be caused by different species, and previous studies have indicated that might have high species diversity in Brazil. During a disease survey conducted in three commercial plantations of in northeastern Brazil, diseased leaves from trees with typical symptoms of CLB were collected, and fungi were isolated. Based on phylogenetic analyses of six gene regions (t, , , , , and ) and morphological characteristics, two new species of were identified. Five isolates were named as and four were named as The pathogenicity to of both species was confirmed by fulfilling the Koch's postulates.
