Caloboletus calopus
Caloboletus calopus is a fungus of the bolete family, found in Asia, Northern Europe and North America. The stout fruit bodies are attractively coloured, with a beige to olive cap up to 15 cm across, yellow pores, and a reddish stipe. It is not typically considered edible due to an intensely bitter taste that does not disappear with cooking.
About Caloboletus calopus in brief
Caloboletus calopus is a fungus of the bolete family, found in Asia, Northern Europe and North America. The stout fruit bodies are attractively coloured, with a beige to olive cap up to 15 cm across, yellow pores, and a reddish stipe. The pale yellow flesh stains blue when broken or bruised. It is not typically considered edible due to an intensely bitter taste that does not disappear with cooking, but there are reports of it being consumed in eastern Europe. Its red stipe distinguishes it from edible species, such as Boletus edulis. Modern molecular phylogenetics showed that it was only distantly related to the type species of BoletUS and required placement in a new genus. In 2014, B. calopus was transferred to the new genus Caloboletes by Italian mycologist Alfredo Vizzini, with C.
calopus designated as thetype species. It measures 7–15cm long and 5 cm wide, with the stipe up to 2–5 cm thick and is either fairly equal in width towards the base or thicker towards the top. The pore surface is initially pale yellow before deepening to an olive-yellow in maturity, and quickly turns blue when it is injured. The pores, numbering one or two millimetres, are circular when young but become more angular as the mushroom ages. The tubes are 2 to 2.5cm deep and are typically above to pink-red below the upper half of the upper stipe with a network of straw-coloured over the top or over the lower half. The yellow flesh has discolouration spreading out from the broken, broken or damaged area and can be strong, spreading out to the base.
