Conteúdo:

Cercospora coffeicola is the causal agent of
brown eye spot, an important disease of coffee (Coffea
arabica) in Brazil. However, atypical symptom as
darker and larger lesions, named black spot, has been
reported in field. In this study, we tested the hypothesis
that the causal agent of black spot belongs to the same
species pathogenic to brown eye spot. Nineteen strains
obtained from diseased coffee found in the five largest
coffee-producing states of Brazil were characterized by
a combination of molecular phylogenic methods, using
a multi-locus approach (internal transcribed spacer regions
and intervening 5.8S nrRNAs, actin, calmodulin,
histone H3, and translation elongation factor 1-alpha),
analyses of morphological markers and pathogenicity.
Strains from brown eye spot and black spot disease on
coffee leaves formed a clade with C. coffeicola strain
from Japan. All strains showed same morphological
characteristics and caused brown eye spot symptoms
in greenhouse. These results confirm that the species
associated with brown eye spot and black spot disease
on coffee leaves is C. coffeicola. Additionally, an
epitype is proposed for C. coffeicola.
