Habitat: Common in conifer forests

Conservation Status: Not of concern

Cortinarius vibratilis has been considered a myxacium. However, recent studies suggest that it is not closely related to typical myxaciums, but instead forms a separate group with species such as C. causticus and C. pluvius. All of these share a bitter taste, easily discovered by licking the viscid cap, have medium-sized to small, rather fragile fruitbodies that feature red-brown, orange-brown, and yellow-brown caps with a whitish edge. The gills are whitish to pale ochraceous, the stipe is usually cylindrical to narrowly clavate, and often tapered at the base, soft and white becoming yellowish, and glutinous. The veil is white. The spores are more or less elliptical, small, and finely ornamented.
