Sutorius eximius is a species of mushroom belonging to the Boletaceae family, within the Boletales order of the Basidiomycota division. This mushroom, previously classified under the genus Boletus, has been reclassified due to molecular phylogenetic studies, which have led to a reevaluation and restructuring of bolete taxonomy. Sutorius eximius is known for its distinctive features and edibility, making it a notable species among mushroom foragers and enthusiasts.

Description

Sutorius eximius mushrooms are characterized by their large, robust stature. The cap can range from 7 to 30 cm in diameter, initially convex before flattening out with age. The cap surface is smooth, often becoming sticky in wet conditions, and displays colors ranging from dark brown to reddish-brown. The pore surface is notable for its fine pores, which are initially pinkish before turning brown with maturity. The stipe is thick and bulbous, often with a reddish-brown hue, and lacks the mycelial cords that are characteristic of some other bolete species.

The spore print of Sutorius eximius is olive-brown, with spores being ellipsoid and smooth. This species is distinguished by its bluing reaction when the flesh is exposed to air, a trait it shares with several other members of the Boletaceae family.

Habitat and Distribution

Sutorius eximius is primarily found in hardwood forests, forming mycorrhizal associations with a variety of trees, including oaks (Quercus spp.), chestnuts (Castanea spp.), and beeches (Fagus spp.). This symbiotic relationship is crucial for the nutrient exchange between the fungus and its host trees. The species is widely distributed in temperate regions, particularly in North America and parts of Europe and Asia, where its preferred forest habitats are prevalent.

Edibility

The mushroom is considered edible and is highly prized in some cultures for its flavor and texture. However, as with all wild mushrooms, caution is advised when foraging for Sutorius eximius, as it can be confused with other, potentially toxic, bolete species. Proper identification by an experienced mycologist or forager is recommended before consumption.

Conservation

While Sutorius eximius is not currently listed as endangered or threatened, its reliance on healthy hardwood forests for survival underscores the importance of conserving these ecosystems. Habitat destruction and pollution pose significant threats to the species, along with other forest-dwelling organisms.
