Distribution: In Europe this species is known from Austria, the British Isles, the Czech Republic, Denmark, Finland, France, Germany, Lithuania, the Netherlands, Norway, Poland, Portugal (mainland, Azores and Madeira Islands), Romania, Russia (Central European Russia and north-western Russia), Spain (mainland and Canary Islands), Sweden and Ukraine. It has been introduced to Africa, Australia, North and South America and the Oriental region ( Kime & Enghoff, 2017).

Remarks: This species is commonly found associated with decomposing deadwood, but also in soils close to deadwood and in leaf litter. The species may have a Lusitanian or Atlantic origin as it is a very common species in the British Isles, but it is nowadays a synanthropic cosmopolitan species ( Kime & Enghoff, 2017).
