Macroscopic features
The hat of the wolf tube is hemispherical to cushion-shaped, but at most is pillow-shaped. It reaches a diameter between 5–10 cm, in some cases up to 18 cm. In youth it has a soft pink frosting. The deep pink colored hat skin becomes visible by scratching. Later, both tones become increasingly dirty, so that the hat takes on a buff or beige-gray color. Greenish or yellowish tones can also be mixed in with this. For a long time it retains more or less large pinkish-red spots and loose residual tires in the middle. The surface is smooth, but hardly gets greasy even in damp weather. The hat skin protrudes slightly.
The tubes are initially colored yellow, soon also tinted olive. They turn blue when pressed. The small pores are only initially orange-yellow, but quickly become blood red. Usually they have a constant color over the entire diameter. They also blue when touched.
The stem becomes 5–10 cm long and between 2–4 cm thick. It has a cylindrical shape, but can be slightly thickened at the base. In the upper part it is colored bright yellow. Towards the bottom, the tone becomes more ocher-yellow. The surface is not wetted and either completely bare or with finely distributed orange-red flakes. The mycelium at the base is whitish.
The meat ( trama ) is clearly tinted yolk yellow. If injured, it immediately turns a clear blue. After several hours it will turn a cloudy yellow again. Often there is no color in the base of the stem. The tube bottom (meat under the tubes) is yellow. The smell is unremarkable; in old age it becomes a bit uncomfortable and resembles the stink umbrella ( Lepiota cristata ). The taste is mild, but also rather unpleasant. When dry, the mushroom smells like coconut flakes.
Microscopic features
The basidia measure 25-35 × 8-11 micrometers. The Zystiden are bottle-shaped, breitzylindrisch, bulgy-spindles to slightly keulig and measuring 40 × 3.5 to 6.25 microns. The spores are spindle-shaped and measure 11-14 × 4.5-5.5 µm. The top layer of the hat initially has more or less erect, but later adjoining hyphae ends . These are 3–6 µm thick; the short-cylindrical end cells are relatively short with a length of 15-25 µm.
Species delimitation
It can be confused with the more common but also rare smooth-stemmed witch's boletus ( Suillellus queletii ). However, it has darker, often brownish hat colors and paler, orange-red pores. In addition, the meat in the base of the stem is clearly purple in color. From above it is very similar to the rose-capped boletus ( Rubroboletus rhodoxanthus ). However, its stem has a striking red network. It can also be confused with the blood-red witch's tube ( Rubroboletus dupainii ). This hat has a smeary hat when it is wet and shiny like a varnish when it is dry, which has stronger, blood to purple colors. All other thick boletus relatives with red pores have a flaky or reticulated stem.
Ecology and diffusion
The wolf boletus is a heat-loving fungus that can be found in base-rich deciduous forests. There it can be found under beeches and oaks. The fruiting bodies appear from August to October.
The wolf boletus is mainly found in southern and southeastern Europe, where it occurs only rarely. Finds that are further north, especially those north of the Alps, are only made very rarely. So far only one find of this kind has been made in Germany. This is located on Schönberg near Freiburg im Breisgau and has not been detected there since 1982.
meaning
The Wolf Röhrling is suspected of being poisonous. Further details on the possible toxic effects are not known due to their rarity.
