Bolet rubis
Chalciporus rubinus
Bolet rubis (Chalciporus rubinus) is a distinctive bolete mushroom characterized by its reddish-brown cap and bright yellow pores that bruise blue when touched. This mycorrhizal fungus forms essential symbiotic relationships with coniferous trees, particularly spruces and firs, facilitating nutrient exchange and supporting forest ecosystem health.

Species Profile
Bolet rubis (Chalciporus rubinus) is a distinctive bolete mushroom characterized by its reddish-brown cap and bright yellow pores that bruise blue when touched. This mycorrhizal fungus forms essential symbiotic relationships with coniferous trees, particularly spruces and firs, facilitating nutrient exchange and supporting forest ecosystem health.
Bolet rubis faces significant threats from habitat degradation and loss of its specialized mycorrhizal forest ecosystems. Climate change and forest fragmentation are disrupting the delicate soil chemistry and host tree relationships essential for this fungal species' survival and reproduction.
Key Facts
Habitat & Distribution
Deciduous and mixed forests, particularly beech and oak woodlands with acidic soils, forming mycorrhizal associations with broadleaf trees. Typically found in mature forest ecosystems with stable soil conditions and established fungal networks.
Threats
Forest habitat loss and fragmentation
Soil acidification and chemical pollution
Climate change affecting mycorrhizal relationships
Loss of host tree species
Overharvesting by foragers
