Pay attention to the leg of the common oak tree: its height is 5-17 cm, most often it is red, dark orange or brown, there may be small greenish spots at the very base. It has the shape of a club, a characteristic tuberous thickening and a mesh pattern along the entire length. Tubular layer: with round and very small red pores, which turn blue with gentle pressure.
Pulp: yellow, turns blue when cut and exposed to air. It does not have a pronounced taste and smell.
Doubles: are absent.
When growing: from late May to early September in the Caucasus, Siberia and the Far East. Although it is a heat-loving mushroom, it can also be found in the Leningrad region.
Application in traditional medicine: is not used, but scientists have learned how to extract the antibiotic boletol from an ordinary dubovik.
Important! The use of an ordinary oak tree along with alcohol can lead to problems in the gastrointestinal tract.
Where can I find: on limestone soils next to birches and oaks in well-warmed and sunny forest areas.
Eating: in dried or pickled form, subject to pre-soaking and boiling, and the water must be drained several times. Although the concentration of toxic substances in the common oak tree is very low, and besides, they are destroyed during cooking, nevertheless, a short temperature treatment can lead to a severe eating disorder. If you add a little citric acid to the jar during pickling, the mushroom will retain the light color of the pulp and will not change it to lilac or purple.
Other names: olive-brown dubovik, poddubnik, dirty-brown bole.
