features

Group photo: fruiting bodies at different ages

The compact hat can be up to 35 cm wide. At first hemispherical, then spread out like a cushion, it becomes irregularly bent with age. The hat is chalk white to off-white when young, while older it tends to be ocher, leather-colored and sometimes slightly green. The hat skin is overgrown with fine tomentose hair, later balding and then often becomes slightly sticky and greasy; it does not turn blue when touched. The tubes are pale yellow at first and then turn green-yellow and pale blue-green. The pores are yellowish only in young mushrooms, but very soon have a reddish tinge and are completely red even before they are fully ripe. The stem becomes 5 to 12 cm long and is often very bulbous and bulbous (4 to 10 cm); mostly it is wider than long and even almost spherical when young. It is covered by a distinctly red net on a yellow background, which finally turns dark blood red, is tightly meshed, hexagonal and sometimes extends to the yellowish base zone. The flesh is whitish, yellow to pale, turns only moderately blue when broken and very rarely turns reddish in color. The smell is young weak and only later and after prolonged lying aasartig .

Ecology and diffusion

The Satan's Röhrling occurs in the entire temperate zone, but it has a distinctly southern distribution in Europe . It grows as a mycorrhizal fungus in deciduous forests, preferably on calcareous soils, and appears there from around June to September.

Species delimitation

The Satan's tubular can be confused in particular with other red-pored thick tubular. The pale-capped purple boletus ( R. rhodoxanthus ) is characterized by a carmine-red stalk net and bright yellow flesh that is blue only in the hat. At higher altitudes, another double can be found with the wine-red purple boletus ( R. rubrosanguineus ). It usually has a narrower stem and a wine-red hat color with age. The inedible bolete ( Caloboletus calopus ) can also resemble Satan's bolete. The tube mouths of the fruiting bodies are yellow and not red in color , except for the ruforubraporus variety . In addition, mushroom pickers often consider the edible witch bolete such as the net-stemmed ( Suillellus luridus ) or the flaky-stemmed witch bolete ( Neoboletus luridiformis ) for the Satan's bolete. However, these form brown-capped fruit bodies, also with olive or red tones. They are less massive and thick and do not have such a strong color contrast between the blood-red underside and the pale hat. The stem surface is also different. In the flaky-stemmed witch bolete, it is netless, covered with red flakes, the net-stemmed stem has a clearer, wider-meshed stem net than the Satan's bolete, on an orange-brown background. In addition, their meat turns blue quickly and clearly on contact with atmospheric oxygen.

Toxicity

Satan's boletus is poisonous ; it contains the glycoprotein bolesatin, which causes severe stomach and intestinal problems. There are no reports of fatal poisoning by boletus.
