rDNA analyses as an aid to the taxonomy of species of Ganoderma

As part of research to implement methods for the identification of Ganoderma species, this paper describes the use of PCR coupled to restriction digestions, single-strand conformational polymorphism (SSCP) and direct sequencing to assay rDNA polymorphism in South American collections of Ganoderma.
