Russula decolorans is a widespread edible ectomycorrhizal fungus in Eurasia 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?
Russula decolorans is common in temperate to subarctic and subalpine areas in Europe, Asia and in 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
Russula decolorans is an ectomycorrhizal mushroom in coniferous forests associating with conifers, especially with pine (Pinus), but also in subarctic and subalpine areas with birch (Betula). It is particularly common in nutrient poor lichen coniferous woodland.
There are no major threats to this species. It is commonly and widely found in woodlands.
No conservation measures are needed for this species since it is widespread and there are no major threats to it.
Use and Trade
Russula decolorans is an appreciated wild mushroom.
