areneissa

Arenes is a genus of fungi belonging to the family Tricholomataceae. These mushrooms are characterized by their fleshy fruiting bodies and are often found growing in terrestrial habitats. The genus was first described by French mycologist Lucien Quélet in 1886. Species within the genus are distributed worldwide, typically inhabiting forests and grasslands.

The cap of arenes mushrooms can vary in shape, from convex to flattened, and often features a smooth or slightly scaly surface. The gills, located on the underside of the cap, are typically decurrent, meaning they run down the stipe. The stipe itself is generally central and may be fibrous. The spore print color for arenes species is typically white to cream. Some species may be edible, while others are not, and caution should be exercised when identifying and consuming wild mushrooms. Research into the biochemistry and ecological roles of arenes continues to expand our understanding of these fungi.
