Molecular marker techniques in the study of wild basidiomycete, are increasingly applied to ecology projects, with special focus on analysis of genetic diversity.Often require altitude sunscreen specialized methods for extracting the DNA of organisms of natural environments, because of the complex compounds that are (carbohydrate polymers) and contaminants from the environment (soil particles).Biological materials used were basidiocarps collected in the forest of Santa Rosa, Guanajuato.And mycelium isolated from these basidiocarps.

In this work we used a DNA extraction method that allowed the PCR amplification, restriction enzyme digestion and Southern hybridization by non-radioactive method.The results were obtained: Amplification of silver lining herbs kidney support the ITS1 region of ribosomal unit of the different species of Basidiomycetes.It was possible to observe the genetic diversity among different species of basidiomycetes and the mycelia.Furthermore, the results also suggest differences in DNA methylation between the vegetative mycelium and mycelium of basidiocarp.

Finally it is noteworthy that there were no previous work on the application of methods of non-radioactive Southern hybridization for analysis of wild Basidiomycetes and this pioneering work in applying this technique.
