Tricholoma atroviolaceum
Description: 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.

Tricholoma inamoenumirksome cavalier, ill-scented tricholoma
Description: Small to medium-sized fungi with wide-spaced, broad gills and a “coal gas” odor. Pale yellow fruitbodies. Coal gas is not something many people get an opportunity to smell nowadays but the odor of these mushrooms is strong and unpleasant for most people; some liken it to a heavy floral odor, such as that of Narcissus.
Distribution: Widely distributed in the Northern Hemisphere
Habitat: Under conifers

Origin: Native
Tricholoma magnivelareAmerican matsutake, white matsutake, pine mushroom
Distribution: . It occurs throughout much of North America, but is most abundant on the West Coast, usually appearing scattered to gregarious under conifers on nutrient-poor soils such as dune sands.
Origin: Native
Tricholoma muricatum
Description: Tricholoma muricatum is one of a confusing bunch of reddish brown-capped, viscid tricholomas, distinguished from the others by its radially fibrillose cap with short grooves at the edge, orange-white gills, brownish orange stipe, and growth with pine.
Habitat: One of the characteristic fungi of the coastal Oregon shore pine woodlands. When found in this habitat, it is fairly easy to identify, but away from coastal pines, identifications in this group become extremely difficult.

Tricholoma nigrum
Description: Tricholoma nigrum is a little-known species, having been described in 1996 from a single collection made along the Oregon coast. Its fruitbodies are medium-sized or larger, and reminiscent of those of T. atroviolaceum, T. atrosquamosum (Chevallier) Saccardo, and T. luteomaculosum A. H. Smith. The cap is moist to somewhat sticky and densely covered with dark gray fibrils and small scales in the center, less so near the edge, the gills whitish to grayish, the stipe whitish, coated with silky fibrils, and sometimes with scattered blackish scales in its upper portion. Microscopically, the key characters are the layer of inflated cells that underlies the cap cuticle and presence of (often inconspicuous) cheilocystidia. The odor and taste are strongly farinaceous. The type collection was made in a shore pine woodland, whereas our collections came from an old-growth, mixed conifer forest dominated by Douglas-fir and western hemlock, with occasional western white pines on nutrient-poor soil.
