Mushrooms are characterized by their yellow caps with a brownish center and scales over the margin, and the conspicuous remains of a partial veil that is left on the stipe.
[2] It was known as an Armillaria for several decades until members of that genus with amyloid spores and lacking black rhizomorphs were transferred to Floccularia in 1987.
Shiny with a light yellow-brown base color, it has one to several cottony zones of partial veil remnants.
[6] The base form of species Floccularia luteovirens is similar in appearance, but can be distinguished from F. albolanaripes by its brighter yellow cap color with raised scales on the surface, and yellowish gills.
In North America, it is found in the Pacific Northwest and the Rocky Mountains, where it occurs in the spring and summer.
