Gomphidius roseus is a less common but widespread edible ectomycorrhizal fungus in Europe associated to the very common Jersey Cow fungus and pines. There is no evi-dence 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?
Gomphidius roseus is less common but widespread in Europe throughout the occurrences of the Jersey cow mushroom to which it is associated.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
Gomphidius roseus grows in Scots pine forests on acidic soil. It is classified as an ectomy-corrhizal fungus forming mycorrhiza with pine (Pinus) but it is also obligatory associated with Jer-sey cow bolete (Suillus bovinus). These three organisms form a three-way mycorrhizal relationship where G. roseus is thought to be parasitic upon the mycelia of S. bovinus.
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.
