About

Rubroboletus rhodoxanthus is a species of bolete in the family Boletaceae, native to Europe. Previously known as Boletus rhodoxanthus, it was transferred in 2014 to the newly erected genus Rubroboletus, based on DNA data. It produces large, colourful fruit bodies with pink patches on the cap, red pores in the hymenial surface and has a robust stem decorated in a dense, red-coloured network pattern. When longitudinally sliced, its flesh is distinctly bright yellow in the stem and discolours blue only in the cap, an excellent diagnostic feature distinguishing it from similar species. The fungus is more widespread in warm broad-leaved forests of southern Europe, where it grows in mycorrhizal symbiosis with trees of the family Fagaceae, particularly oak (Quercus) and beech (Fagus). However, it is rare in northern regions and regarded as critically endangered or extinct in some countries. Rubroboletus rhodoxanthus is generally regarded as inedible and may cause adverse gastrointestinal symptoms if consumed.
