Paxilliini

Paxilliini is a tribe of fungi belonging to the order Boletales. This group is characterized by the presence of basidiocarps, which are the fruiting bodies of the fungi. A defining feature of many paxilliini species is the formation of gills or gill-like lamellae on the underside of the cap, which distinguishes them from many other bolete-forming fungi that typically have pores. The lamellae can be adnate or decurrent, meaning they are attached to the stem or run down it, respectively.

The caps of paxilliini fungi are often fleshy and can range in color from various shades of brown to yellowish or even reddish-brown. The stems are typically central and may be solid or hollow. Mycorrhizal associations are common within this tribe, indicating a symbiotic relationship with plant roots, where the fungus helps the plant absorb nutrients from the soil in exchange for carbohydrates.

While some species within paxilliini are considered edible, caution is advised as others can be toxic. Consumption of certain members of this tribe has been linked to gastrointestinal distress and, in some cases, more severe allergic reactions, including potential immune responses. Due to the variability in edibility and toxicity, accurate identification by experienced mycologists is crucial before considering any species for consumption. Research into the biochemistry and ecological roles of paxilliini continues to be an area of interest within mycology.
