摘要

Typical anthracnose symptoms were observed on leaves and fruit of achachairu (Garcinia humilis) in a producing region in Pernambuco, Brazil. The fungi were isolated from necrotic lesions on leaves and fruit to identify the causal agent and subjected to morphological and phylogenetic characterization. Based on these analyses, the species C. theobromicola and C. siamense were identified. The pathogenicity test confirmed that these two species are the causal agents of anthracnose on G. humilis. This is the first report of C. siamense and C. theobromicola causing anthracnose on leaves and fruits of G. humilis worldwide. Here, we also report these two species as pathogens on the fruit of G. brasiliensis (bacupari).
