Is Bitter beech bolete Toxic?
Bitter beech bolete is identified as non-edible due to its bitter taste. Consumption of this mushroom could potentially cause gastrointestinal discomfort. It's commonly found on neutral or alkaline soil beneath beech trees, deciduous oaks, and occasionally under pine and spruce trees. It forms symbiotic relationships with the root systems of these trees, functioning as an ectomycorrhizal fungus. An additional risk is that it can be confused with the more toxic Rubroboletus satanas. Given these factors, it's advised not to consume bitter beech bolete.
