02Description

Species Profile

Suillus flavidus is a bolete mushroom in the genus Suillus native to Europe. It is considered endangered in the Czech Republic and Switzerland. It is also considered edible, but with an unpleasant taste.

Suillus flavidus faces severe population decline primarily due to habitat loss from deforestation and urban development in its limited range. The species' obligate mycorrhizal relationship with specific coniferous trees makes it particularly vulnerable to forest fragmentation and changes in forest composition.
