Volunteers from the San Diego Mycological Society have been vouchering some of the mushroom specimens gathered during their forays in the SD Herbarium at the San Diego Natural History Museum, with the goal of eventually creating a synoptic collection of mushrooms for the county.
In 2014 they began preserving tiny tissue samples from the specimens so they could be sent to the University of Guelph (Canada) for barcoding. Barcoding is a new system of species identification and discovery that is being used worldwide (see iBOL ). The sequence of a short section of DNA taken from a standardized region of the genome provides a unique code that can be used to identify different species.
