Tricholoma atroviolaceum

Distribution: Pacific Coast Pacific Coast

Conservation Status: Not of concern

Identification Notes:

Tricholoma atroviolaceum is characterized by medium-sized to large hard-textured fruitbodies with a broadly convex to plane cap, densely covered with small blackish violet to violaceous gray-brown fibrillose scales, and often with the edge split radially in age. The flesh of the cap often stains reddish gray when cut, the gills are cinnamon- or pinkish gray-tinged, and the stipe is thick, brownish in age, and sometimes has an enlarged base. The flesh has a mildly to strongly farinaceous odor and somewhat bitter taste. T. atroviolaceum occurs in northern California and the PNW under conifers, but usually not in large numbers. Apparently it is restricted to the Pacific Coast.
