The cap was mostly tan and reminded me of an English muffin (pic 2). The gills has a purplish hue and the stem was short and bulbous.
Spotted along a trail in a deciduous forest at Pinnacle Mountain State Park.
This species is mycorrhizal: It exists most of the time as a network of cells (mycelium) connected to tree roots, in a symbiotic relationship with the tree. (Many trees fare poorly without their fungal partners.) When ready to reproduce, the mycelium sends up the mushroom aboveground—this is the reproductive structure. Spores are produced in these structures and are released to begin new mycelia elsewhere. The mycelium of a mushroom can live for decades.
