Assessment Notes

Taxonomic notes

Why suggested for a Global Red List Assessment?

Rare and distinctive species. Large fleshy bolete with beautiful pinkish red to carmine red cap, yellow pores and stem. Threaten by loss of habitat, air pollution, modern forestry. It is red-listed in 16 European countries. Small populations.

Preliminary global red-list assessment: DD (Data Deficient)

Obviously a rare species, red-listed in all European countries (16) where it is known.
Probably not the same species in Asia and North America

More information needed: If the Asian and north American reports of the taxon is the same taxon as reported in Europe. Also about its habitat and the status of the population/ha bitat.

Geographic range

In Europe widespread but not found in the far north and generally more common in south. Localities in North America and Japan. Extinct(?) in Netherlands.

Population and Trends

Small populations. Europe : Vulnerable?
Red listed in 11 countries with IUCN categories and in 5 countries with national red-list categories.

Population Trend: Stable

Habitat and Ecology

Broadleaf forests, mycorrhizal with oaks (Quercus), beech (Fagus) or sweet chestnut (Castanea sativa)

Temperate Forest


Loss of habitat, air pollution, modern forestry. In some countries could be endangered by side effects of harvesting edible mushrooms in enormous quantities (raking of litter and soil, intensive trampling and soil erosion, the deposition of waste etc). These methods may damage the habitats of the edible fungi, perhaps in an irreversible way.

Logging & wood harvesting

Conservation Actions

Protection of ancient woodland and especially of known sites, where a management system ensuring the right age profile in the stands of the tree partner should be implemented.

Research needed
