Stem-end rot is the major postharvest disease of coconut in Brazil. The fungus Lasiodiplodia theobromae is the only species that has been reported to be associated with this disease. However, an accurate study elucidating the true identity of this pathogen with molecular tools has never been carried out. In recent years, new species of Lasiodiplodia have been proposed after molecular studies were performed, indicating the existence of a species complex behind L. theobromae. The aims of this research were to study the etiology of the postharvest stem-end rot of immature coconut based on a combination of morphological and phylogenetic analyses, to establish the phylogenetic position of such taxa and to assess the pathogenicity of each taxon. Four species were identified: Lasiodiplodia brasiliense, L. egyptiacae, L. pseudotheobromae and L. theobromae. All of the species were distinguished morphologically and phylogenetically and were proven to be pathogenic to coconut. Lasiodiplodia theobromae is the most common and the most aggressive species. This work represents the first reports worldwide of the presence of three different species of Lasiodiplodia as causal agents of postharvest stem-end rot of immature coconut. Such results are critical for further studies on management measures, quarantine programs or the development of stem-end-rot-resistant coconut varieties.} }
