Description

When Fusicoccum luteum was first described in 1985, it was not found sporulating in nature and its teleomorph was not known. Recently, a Botryosphaeria sp. was found on grapevines in Portugal, and the anamorph in culture resembled F. luteum. Nucleotide sequence of the nuclear rDNA internal transcribed spacer ITS2 distinguished isolates of this fungus from others in the B. dothidea complex, and the teleomorph, Botryosphaeria lutea, is described here as new. Although the teleomorph of B. lutea is morphologically indistinguishable from others in the B. dothidea complex, the holomorph is clearly distinguished by a yellow pigment proced in culture.
