Small and fragmented population in humid warm temperate-Mediterranean-subtropic cliamatic zones. Potentially endangered by habitat destruction (clear felling)/decline in Europe. Global population status unclear and evaluation is thus difficult until more data is available, DD is suggested.

North America, S. America, Mediterranean Europe, SE Asia, Australia/New Zealand, S. Africa. Warm temperate- Mediterranean - subtropical distribution.

Currently less than 200 records on GBIF; Cosmopolitan but fragmented distribution. Population in Europe is small and potentially endangered due to clear-cutting of habitats. Along the French Atlantic coast where it occurs in litter of Robinia its habitats seem to be threatened by nature conservation measures aiming at eradicating Robinia (a non-native and invasive species in Europe).
A more extensive population with a wide distribution seems to be present in N. America. Current trend on a global scale is uncertain.

Estimated number of localities: 400
Estimated number of functional individulas: 800
Estimated number of mature individuals: 8000

EOO: 203 million km2
AOO: 332 km2

Saprotrophic species growing in humid deciduous woodland. In Europe along streams and in litoral woodland with Mediterranean vegetation, sometimes in litter of Robinia pseudoacacia on sandy soil. Thermophilous, in somewhat humid habitats, subtropical-Mediterranean.

Europe: habitat destruction due to clear-cutting (and nature conservation activities eradicating Robinia). Potential threats in N. America are unclear.

Known localities should be monitored to get a clearer picture of the current population status.
