The mushroom season in the Novosibirsk region is in full swing, with locals actively collecting orange-cap boletes. A common question arises: are mushrooms that turn blue when cut dangerous?

According to a local mycologist, the bluing effect in certain mushrooms is a natural chemical reaction and doesn’t necessarily indicate toxicity. This phenomenon is primarily observed in orange-cap boletes, slippery jacks, some boletes, and Boletus luridus.

The blueing is caused by pigments that react with oxygen. These mushrooms contain specific red-yellow pigments that oxidize upon exposure to air, resulting in the blue discoloration.

While the Satan’s bolete can also turn blue, it is not found in the region. It is crucial to avoid confusion with the edible Boletus luridus.

Boletus luridus is considered edible but should not be consumed with alcohol. It can interfere with alcohol metabolism, leading to adverse effects.

Orange-cap boletes can cause allergic reactions in some people, so moderation is key when trying them for the first time. The blue color of these mushrooms will typically turn black during cooking, which is a normal occurrence.

Pre-boiling any mushroom is recommended to minimize the risk of adverse reactions. And remember, never pick or eat mushrooms you cannot confidently identify.
