Em 2003 e 2004, os fungos Aspergillus spp., Chaetomium spp., Cladosporium sp., Fusarium spp., Paecilomyces sp., Penicillium spp., Pestalotiopsis sp., Phomopsis sp., Aureobasidium pullulans (de Bary) Arnaud e uma levedura não identificada foram isolados de sementes de mangaba (Hancornia speciosa Gomes) coletadas em três localidades do Cerrado do Brasil. Testes de patogenicidade e o subsequente reisolamento de Fusarium sp. (CPAC-1857), Pestalotiopsis sp (CPAC-1838 e CPAC-1844)., Phomopsis sp. (CPAC-1863) e de A. pullulans (CPAC-1845) de mudas de mangabeira inoculadas artificialmente comprovaram os postulados de Koch.

In 2003 and 2004, the following fungi were found in mangaba (Hancornia speciosa Gomes) seeds in the Brazilian Cerrado: Aspergillus spp., Chaetomium spp., Cladosporium sp., Fusarium spp., Paecilomyces sp., Penicillium spp., Pestalotiopsis sp., Phomopsis sp., Aureobasidium pullulans (de Bary) Arnaud and an unidentified yeast. Pathogenicity tests and subsequent reisolations of Fusarium sp. (CPAC-1857), Pestalotiopsis sp. (CPAC-1838 and CPAC-1844)., Phomopsis sp. (CPAC-1863) and A. pullulans (CPAC-CPAC-1845) from artificially inoculated mangabeira seedlings fulfilled the Koch's postulates.

Phoma multirostrata foi isolado de mudas de baru com sintomas de lesões foliares marrons em condições naturais, no Distrito Federal, em 2004. Testes de patogenicidade e o subsequente reisolamento do fungo comprovaram os postulados de Koch. A ocorrência de mancha foliar de baru causada por P. multirostrata é relatada pela primeira vez no Brasil.

The fungus Phoma multirostrata was isolated from infected baru plants with large leaf spot symptoms in Brasília, Brazil, in 2004. Pathogenicity tests under greenhouse conditions and subsequent reisolation of Phoma multirostrata from artificially inoculated baru seedlings fulfilled the Koch´s postulates. Symptoms of leaf spot appeared four days after inoculation in 100% of the inoculated seedlings. The present report is the first on the occurrence of leaf spot of baru caused by Phoma multirostrata in Brazil.
