Kuehneromyces mutabilis is widespread edible wood inhabiting fungus widely distributed in northern Europe and Asia and North America. 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?
Kuehneromyces mutabilis is common and widely distributed throughout Europe, also common parts of North America and occurs in Russian parts of Asia, Japan and in Australia. 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
Kuehneromyces mutabilis is a wood-inhabiting fungus normally growing in tufts, on stumps, felled trunks and logs of broad-leaf trees, particularly birch, more rarely on coniferous wood.
Use and Trade
Kuehneromyces mutabilis is a a fairly good edible mushroom. Only experienced fungi foragers should consider gathering this species, because it can be confused with the poisonous Funeral Bell, Galerina marginata.
