Calocybe gambosa is widespread edible saprobic fungus in western Europe. There is no evidence of decline. It can be locally abundant where suitable habitat exists. Therefore, it is assessed as Least Concern (LC).
Why suggested for a Global Red List Assessment?
Calocybe gambosa is distributed throughout Europe, infrequent in most parts, but on calcareous soils locally very common. The area of occupancy (AOO) of this species is much larger than 2,000 km², and its extent of occurrence (EOO) is much larger than 20,000 km².
Population and Trends
The population size is likely to be very large since this is such a widespread species and more or less stable. There is no indication of any decline.
Habitat and Ecology
Calocybe gambosa is a decomposer fungus growing commonly in richer, often calcareous, soils in natural and semi-natural grasslands, meadows, pastures, sometimes also in gardens and deciduous forests. Typically form fairy rings, which may become huge and be several hundred years old.

There are no major threats to this species. It is common and widely distributed in calcareous grasslands.
No conservation measures are needed for this species since it is widespread and there are no major threats to it.
