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. The family contains 34 genera and over 1000 species. The majority of species in the Hygrophoraceae are ground-dwelling, though a few (such as Chrysomphalina species) occur on wood, or on mosses (Arrhenia species), or herbaceous stems (Eonema pyriforme). Most are found in woodland, though (in Europe at least) Hygrocybe species are typical of waxcap grasslands. Read more on Wikipedia.
