Helvella lacunosa

The Black Helvella, another woodland species, is rather less frequent than the white species.

One of the Waxcaps, agarics with characteristically waxy caps and stems. This is one of the more common species. With reduction in the principal waxcap habitat, unimproved grassland, the genus Hygrocybe is on the decline, and the British Mycological Society is currently running a waxcap-grassland survey.
