Armillaria sinapina
honey mushroom

Conservation Status: Not of concern

Identification Notes:

A. sinapina differs only slightly in appearance from A. ostoyae, with a cobwebby veil and slightly smaller cap scales, grows singly or in clusters of only a few individuals, and in the PNW appears to also grow primarily on conifers. Its most distinctive feature in eastern North America, the bright yellow color of its veil, is lacking, or at least inconsistent, in PNW specimens. Thus, this species often cannot be distinguished from A. ostoyae. A. ostoyae is a virulent pathogen of conifers, and, although edible when young, is considered worth collecting by relatively few mycophagists.
