The species usually grow on the ground, but exceptions occur in

rotten wood; they commonly grow in clusters, many are fragrant
and appear in the late autumn or early winter ; a few are

thick and often of a wax-like substance, or with Cantharellus, where
the gills are very thick and fold-like, or Lentinus, Panus or Xerotus,
where the substance is leathery and the habitat usually stumps.
