title: Conspecificity of Hanseniaspora nodinigri and Hanseniaspora vineae: comparison by DNA reassociation.
abstract: Hanseniaspora nodinigri Lachance 1981, found in black knots (caused by Dibotryon morbosum) of Prunus virginiana, was described as a new species, some time after publication of the extensive study by Meyer et al. (1978) on the systematics of Hanseniaspora Zikes and its imperfect counterpart Kloeckera Janke. Lachance delimited the species from other members of the genus because of absence of growth on glucono-delta-lactone. He also stated that this species, although evidently similar in many ways to H. vineae van der Walt et Tscheuschner and H. osmophila (Niehaus) Phaff et al., has 'diverged from them, possibly in its adaptation to growth in association with black knots'.
