Justification

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).


Taxonomic notes


Why suggested for a Global Red List Assessment?


Geographic range

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.

Population Trend:


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.

Boreal Forest

Threats
