Abstract

An undescribed Curvularia sp. was isolated from the leaf spot disease of Barbados Lily (Hippeastrum striatum (Lam.) Moore). Phylogenetic analyses of combined ITS, 28S, GPD1 and TEF1 sequence data place nine strains of this species in the trifolii-clade, but they clustered together as an independent lineage with strong support. This species was morphologically compared with related species in the trifolii-clade. Based on differences in morphology and phylogeny, it is concluded that this species is a new taxon, introduced as Curvularia microsporasp. nov. Pathogenicity testing determined the new species to be pathogenic on H. striatum.
