The overall correspondence of the RFLPs between R. messapica and M. messapicoides adds molecular evidence to the relatedness of Russula and Macowanites, and suggests the possibility that M. messapicoides is recently derived from R. messapica. Fomitopsis cajanderi in Europe - Evidence from mating experiments. Kotl et Pouz in Europe is confirmed by mating experiments. The taxonomical and ecological implications of the results are discussed. Martin, M. P., N. Hogberg, et al.
Molecular analysis confirms morphological reclassification of Rhizopogon.
PCR was used to amplify ribosomal internal transcribed spacer and 5.8 S DNA from type material of Rhizopogon colossus var. Different restriction enzymes were used to digest these amplified rDNAs to find polymorphisms useful in identification. Karen, O., N. Hogberg, et al. Inter- and intraspecific variation in the ITS region of rDNA of ectomycorrhizal fungi in Fennoscandia as detected by endonuclease analysis. Polymorphisms were due to length mutations, ranging from 5 to 15 hp in four of the seven polymorphic species and mutations in endonuclease restriction sites in six species, mostly affecting only one endonuclease, but in two species two endonucleases.
