Suillus grevillei is a widespread edible ectomycorrhizal fungus in Eurasia and North Ameri-ca. There is no evidence of decline. It can be locally abundant where suitable habitat ex-ists. Therefore, it is assessed as Least Concern (LC).
Why suggested for a Global Red List Assessment?
Suillus grevillei is common in Europe, Asia and North America. 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
Suillus grevillei is very common in grass- and woodlands (forest, plantations, gardens and parks) under larch (Larix) in, on sandy, humus-rich or fertile soil. It often fruit in large numbers. It is an ectomycorrhizal mushroom associating with larch (Larix), rarely with Pseudotsuga.
No conservation measures are needed for this species since it is widespread and there are no major threats to it.
Use and Trade
Suillus grevillei is an edible mushroom, but is not one of the most appreciated of boletes.
