Clustered Brown Bolete

Aureoboletus innixus, the clustered brown bolete, is a mycorrhizal basidiomycete fungus in the family Boletaceae native to eastern North America, particularly associated with oak (Quercus) forests from New England south to the southeastern United States. The fruiting bodies are medium-sized boletes with a brown, velvety to dry cap surface, yellow to olive-yellow pores and tubes on the underside, and a stipe that may have a yellowish ground color with brownish fibrils. A distinctive feature is the tendency to fruit in clustered groups at the base of oak trees, sometimes arising from a shared mycelial cord or attached to each other at the stipe bases. The pores do not blueñ when cut or bruised, distinguishing it from some other boletoid species. A. innixus forms ectomycorrhizal associations with oaks, providing trees with enhanced nutrient and water uptake in exchange for photosynthetic carbohydrates. The species has not been formally evaluated by the IUCN for conservation status. It is considered a relatively uncommon but regularly encountered species in appropriate oak woodland settings in the eastern US.
