is a rather common and widespread edible ectomycorrhizal mushroom in northern Europe 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).
is widespread in Europe and North America. It is common in the northern parts, less so to the central and southern parts. 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 as there is no indication of any decline.
Population Trend: stable
Habitat and Ecology
forms mycorrhizae with conifers. In Europe these are especially with Picea
spp. on acidic, mossy ground. On the west coast of the United States, associations are most common with Sitka Spruces (Picea sichensis
) and Giant Redwoods (Sequoiadendron giganteum
). In the Rocky Mountains it associates with Engelmann Spruce (Picea engelmannii
) and Blue Spruce (Picea pungens
), and in northeast North America with hemlocks.
There are no major threats to this species.
No conservation measures are needed for this species since it is widespread and there are no major threats to it.
Use and Trade
is an edible mushroom, more commonly consumed in Europe than in North America.
