Distribution: C. acutus occurs in nutrient-poor conifer forests, often on moist sites in litter, and can be found throughout the north temperate regions.
– silvery-violet Cortinarius, pearly webcap
Habitat: C. aurantiobasis tends to occur in wetter habitats with conifers, often near western hemlock and/or Sitka spruce, and frequently among sphagnum or other mosses.
– gypsy, gypsy mushroom
Distribution: Common in certain years in the PNW, but becomes less abundant inland and to the south
– cinnamon Cort, cinnamon webcap
Habitat: Western conifer forests, extending from lower elevations into the higher mountains
– belted slimy Cortinarius
Distribution: Common and widespread
Habitat: C. croceus occurs throughout north temperate forests and into alpine and arctic areas. It grows with various conifers, as well as hardwoods including beech, birch, and willow.
– deadly Cortinarius, goldband webcap
Habitat: C. gentilis has a broad ecological range, occurring in moist environments as well as drier, upland conifer sites. During the summer in the western mountains it can be very common, often fruiting in groups, sometimes from well rotted woody debris.
– bulbous Cortinarius, blue-foot webcap
– sooty olive Cortinarius, bitter webcap
– spotted Cort, viscid violet Cort
– brown Cortinarius, hoary webcap, woolly webcap
Distribution: Widespread, but variable in its fruiting, in some years being rather common and in others being absent.
Habitat: C. laniger is characteristic of boreal and montane conifer forests.
Distribution: Cortinarius montanus can be very common and widespread, but often occurs as one or a few fruitbodies at a time.
Habitat: Common in older, cool, moist conifer forests.
– slimy Cortinarius, orange webcap
Distribution: C. muscigenus varies in abundance from year to year, and in some seasons can be very common.
Habitat: mid- to high elevation conifer forests
– purple-staining Cortinarius
Habitat: Occurs in a variety of habitats with different conifers and is more frequent in moist areas. Most commonly found along the coast, especially with Sitka spruce.
– blood-red Cortinarius, northern red-dye, blood-red webcap
– little brown Cortinarius
Habitat: Widespread species found in a variety of habitats including pine forests and alpine areas with dwarf birch
Distribution: Varies in abundance from year to year
Habitat: Low to mid-elevation conifer forests
Habitat: C. salor is found in a wide range of forest types
– western red-capped Cortinarius, western red-dye
– pungent Cort, lilac conifer Cortinarius, gassy webcap
Habitat: Abundant in the far-western mountane and boreal regions, but is much less frequent in the Rocky Mountains.
– pointed Cortinarius
Habitat: Coastal conifer forests from northern California to southern Canada.
Habitat: Western North America, occurring both in Rocky Mountain spruce-fir forests and the forests of the Cascades and coastal ranges.
Habitat: Common in conifer forests
– violet Cort, violet Cortinarius, violet webcap
Distribution: In some years it is difficult to find but in general it is commonly encountered, but usually in small numbers.
Habitat: Widespread in older forests in PNW region, but much less common in the interior mountains than nearer the coast.
