Hygrocybe irrigata (syn. Hygrocybe unguinosa) is a fairly rare waxcap of cropped pasture, churchyards and open woodlands. Hygrocybe unguinosa, the Slimy Waxcap, is an autumn and early winter species.
Like so many of the waxcaps, this mushroom is much more common in upland areas of acid soil, but it has also been found in lowland grassland and woodland edge habitats including the downlands of southern England.
