There are a few look-alike species that can be mistaken for the bicolor bolete (Boletus bicolor), but it is important to note that these look-alikes are not only non-edible but also potentially poisonous. One such species is Boletus sensibilis, commonly known as the sensitive bolete or the red-mouth bolete.
One of the key differences between the bicolor bolete and Boletus sensibilis is the immediate bruising reaction. When the flesh of Boletus sensibilis is bruised or cut, it quickly turns blue or green, which is a distinct characteristic not seen in the bicolor bolete. This immediate bruising reaction is a useful identifying feature to differentiate the two species.
Another important difference is the toxicity of Boletus sensibilis. While the bicolor bolete is considered edible and safe for consumption, Boletus sensibilis is known to be poisonous. Ingesting this species can cause stomach upset and, in some cases, a severe allergic reaction. It is best to avoid consuming any mushrooms that resemble Boletus sensibilis to prevent any potential health risks.
B. miniato-olivaceus is another species that can be mistaken for the bicolor bolete. This species has a yellow stem and a cap coloration that is slightly lighter than the bicolor bolete. While B. miniato-olivaceus is not known to be poisonous, it is not widely considered edible either. It is generally recommended to exercise caution when consuming mushrooms that resemble B. miniato-olivaceus, as they may not have desirable taste or texture.
To summarize the differences, Boletus sensibilis has an immediate bruising reaction and is poisonous, causing stomach upset if ingested, and in some cases, a severe allergic reaction. B. miniato-olivaceus has a full yellow stem and slightly lighter cap coloration. These differences in appearance and characteristics can help in distinguishing them from the bicolor bolete.
It is important to note that accurately identifying mushrooms can be a complex task, and it is always recommended to consult with an experienced mycologist or mushroom expert before consuming any wild mushrooms.
