Lyophyllum decastes is a species complex. In the San Franciso Bay Area, the common form has grey-brown caps. It often fruits in large clumps which are sometimes mistaken for Armillaria mellea when the latter fruits in clusters from buried wood. The Honey Mushroom, however, differs by having a yellow-brown to reddish-brown cap with a slightly scaly disc and an annulus.
