 As a result, the Hygrophoraceae as currently understood have no known morphological features in common that define them (synapomorphy).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.
