ABSTRACT
Many species of basidiomycetous fungi are of considerable economic importance. This group of fungi includes edible mushrooms, wood rotters, and serious crop pathogens. However, the application of molecular genetic techniques to improvement or control of these fungi has lagged behind progress in other areas due to the lack of a suitable model system that can be manipulated in the laboratory. The agaric Coprinus cinereus offers many technical advantages and appears to be particularly relevant to ongoing studies that use hymenomycetes of greater commercial value.
