Russula aeruginea is a widespread edible ectomycorrhizal fungus in Eurasia and North America and 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?
It is common in temperate and boreal Europe, Asia and also widely distributed 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 aeruginea is an ectomycorrhizal mushroom associating with birch (Betula spp) in forests and parks. It often occurs in coniferous forests, but then almost always under birch. St common on acid, sandy or peaty soils, occasional on more rich soil were it possibly may associate with conifers.
