Agrocybe praecox is an early-fruiting mushroom appearing late spring and is recognized by a tan-brown to biscuit brown, smooth to cracked in dry weather, sometimes appendiculate cap (3-6 cm broad), closed gills, and tendency to have pallid rhizomorphs (root-forms) at the base.
It is a variable fungus emerging from areas that have been spread with wood chips used in landscaping.
Agrocybe praecox is one of a complex group of fungi that are very difficult to separate in the field. Note: In some field guides this mushroom is recorded in the family Bolbitiaceae.
