The Hygrophoraceae are a family of fungi in the order Agaricales. Originally conceived as containing white-spored, thick-gilled agarics (gilled mushrooms), including Hygrophorus and Hygrocybe species (the waxcaps or waxy caps), DNA evidence has extended the limits of the family, so it now contains not only agarics, but also basidiolichens and corticioid fungi. Species are thus diverse and are variously ectomycorrhizal, lichenized, associated with mosses, or saprotrophic. The family contains 25 genera and over 600 species. None is of any great economic importance, though fruit bodies of some Hygrocybe and Hygrophorus species are considered edible and may be collected for sale in local markets.
