摘要：

Plants of the genus Myrciaria are commonly cultivated in the northern region of Brazil for fruit production. Symptoms of leaf spot in camu-camu (Myrciaria dubia) trees are frequently observed. The objective of this study was to identify the etiological agent associated with anthracnose in camu-camu using the concept of morphological and phylogenetic analyses. Leaves with symptoms of anthracnose were collected from camu-camu plants in the state of Roraima, Brazil. Morphological identification; sequencing analysis of CAL, GAPDH, CHS-1 and TUB2 gene regions; a pathogenicity test and reisolation of the fungus from symptomatic artificially inoculated plants confirmed C. theobromicola as the causal agent of the disease. This is the first record of C. theobromicola causing anthracnose in camu-camu in Brazil.
