Armillaria gallica – bulbous honey fungus, honey mushroom
Description: A. gallica, probably the most common honey mushroom east of the Rockies, appears to occur only rarely in the PNW. It has a white cobwebby veil, pinkish brown coloration, and bulbous-based stipe, and occurs singly or in groups, not clusters, on or near logs, stumps, or bases of broad-leaved trees such as willow.

Armillaria mellea – honey fungus
Description: Grows in dense clusters with convex caps, which become umbonate to slightly depressed. The cap surface is pale yellow-olive to orange-brown, darker at the center, with small, ale to dark brown scales. The gills are decurrent and cream. The stem is cream at the top, becoming dark brown at the base, with a conspicuous ring, often edged in deep yellow.
Habitat: woodlands, parklands, and gardens
Substrate: trunks, stumps, or roots

Armillaria nabsnona – honey mushroom
Description: A. nabsnona was named only in 1996, and so is not widely recognized by mushroom-hunters; thus, it is probably more common than we think. It has a reddish brown smooth cap, stipe that is pale in the upper portion and gradually darkens downward, and grows singly or in groups, but not clusters, in fall or spring on the wood of broad-leaved trees, especially alder. It is thought to be restricted to the Pacific Coast and little is known about its edibility.

Armillaria ostoyae – dark honey fungus, honey mushroom
Description: A. ostoyae probably is our most common honey mushroom. It usually grows in clusters, mostly on conifers, but also on broad-leaved trees and shrubs such as willow and salmonberry; both the clusters and the individual mushrooms can be quite large. The caps are brown and usually covered with dark scales, a fairly well defined brownish ring is present on most fuitbodies, and the stipes often taper to pointed bases where they fuse in clusters. At other times, the bases may be somewhat enlarged.
Habitat: Under conifers
