Abstract

MACEDO, Davi Mesquita de  and  BARRETO, Robert Weingart. First record of Botryosphaeria ribis associated with leaf spots on Magnolia aff. candollei in Brazil. Braz. J. Microbiol. [online]. 2008, vol.39, n.2, pp.321-324. ISSN 1517-8382.  http://dx.doi.org/10.1590/S1517-83822008000200023.

A leaf spot disease was observed attacking some Magnolia aff. candollei plants grown in a private garden in the city of Rio de Janeiro, RJ, Brazil. Such leaf spots coalesced and led to extensive blight of foliage. A fungus was clearly associated to the disease symptoms and was identified as Botryosphaeria ribis. Its anamorph, Fusicoccum ribis, was also present, although less abundant than the teleomorph. This is first report of this fungus on this host in Brazil and the first record of any fungal disease on a member of the genus Magnolia in Brazil.

Keywords : Magnoliaceae; ornamental plant; plant disease; plant pathology; taxonomy.
