Cortinarius magnivelatus Cortinarius magnivelatus appears to be one of the more widespread species. It is rather thick-fleshed and tough, and at first white overall because of the heavy veil that covers the stipe and gills. In age the cap develops yellowish to brownish colors. The gills are white to grayish then brown from the spores, and often forked near the stipe. The stipe is rather long and bulbous with a slightly tapered base. The veil is persistent, often covers much of the stipe, and is firmly attached to the edge of the cap. The flesh is white, and the odor is not distinctive. The spores are rather large, up to 12 um long, and strongly ornamented.
Cortinarius malachius C. malachius is somewhat similar to C. alboviolaceus but it has a grayish white to grayish brown cap that may have lilac colors when young, and with a finely scaly surface when dry.
Cortinarius metarius
Cortinarius mikedavisii
Cortinarius miniatopus
Cortinarius montanus Cortinarius montanus varies in color but is usually fairly easy to recognize. As with many phlegmaciums it is medium-sized to large and rather fleshy with a distinct bulbous base that is covered at first by a distinct pale yellow-green veil and basal mycelium. Typically the cap is viscid, variegated and spotted hazel brown to deep brown with light yellowish olive colors on the margin, and typically becomes more brownish in older specimens. The flesh is whitish or tinged with the colors of the cap, and in the stipe is whitish in the center and bluish near the surface; the odor is not distinctive. The gills are close, rather narrow and light yellowish olive to olive at first, eventually becoming more brownish. The stipe is bluish to grayish blue beneath white silky fibrils when fresh and sometimes discolors purplish when handled. The spores are elliptical and distinctly ornamented. Cortinarius montanus can be very common and widespread, but often occurs as one or a few fruitbodies at a time.

Cortinarius multiformis
Cortinarius muscigenus Cortinarius muscigenus is a cylindrical-stiped species with a viscid cap and stipe classified in subgenus Myxacium. The myxaciums have a universal veil composed of patches and fibrils that is covered with gelatinous material when fresh and that, in most species, breaks into bands and patches as the stipe elongates. These species can be split into two groups based on the presence or absence of clamp connections. C. muscigenus is a member of the former group, which is related to the secotioid species Thaxterogaster pinguis. It is a medium to large species with a strongly gelatinous, brownish orange to brownish red or ochraceous brown cap, which often is darkest in the center and striate near the edge. The flesh is fibrous, white to yellowish, and typically turns brownish in the lower stipe. The gills are grayish white or grayish brown then cinnamon in age. The stipe is whitish, except for the inner veil which is typically bluish violet, sometimes very faintly so. The spores are almond-shaped and coarsely ornamented. C. muscigenus varies in abundance from year to year, and in some seasons can be very common.

Cortinarius variosimilis Cortinarius variosimilis is a close, but distinct, relative of C. varius of Europe. In many ways, it is a pale form of the latter, lacking its distinctly bright lilac-blue gills and the strong yellow-brown to orange-brown colors of the cap. C. variosimilis has a yellow-brown cap often with white veil remnants along the edge, the gills are pale lilac or almost lack lilac color, and become gray-brown. The stipe is clavate, white or pale pinkish buff, and often coated with wooly white veil material. Potassium hydroxide turns the white flesh bright yellow. Broad
var. montanus Cortinarius venetus var. montanus can be found in our region with conifers; its color is more olive-green to yellow-green, the cap is finely tomentose when fresh, and it has a sulfur-yellow veil when young. It has rounded, finely ornamented spores and fluoresce bright yellow in ultraviolet light.
