Cashew trees (Anacardium occidentale) are found throughout the world, and they occupy a prominent place among tropical fruit plants. Since 2014, an inflorescence oversprouting symptom has been observed in cashew trees in Maués, in the state of Amazonas, Brazil (57°43?07? W, 03°22?14? S). This symptom is characterized by excessive proliferation of inflorescences. Symptomatic samples were sterilized with 70% ethanol and 1.5% hypochlorite and then transferred to potato dextrose agar (PDA) and incubated at 25°C for 3 days. Morphological and molecular identifications were performed with monosporic isolate. PDA colonies produced a carmine-red pigmentation. Based on morphological and phylogenetic analyses, isolates were identified as belonging to the Fusarium decemellulare species complex.
