This is one of the classic Cortinarius
species, which is quite
distinctive with the combination of its colors -- red brownish cap with
distinctly white marginal zone and pale bluish stipe with violet context. In
some collections the stipe is tapering. This species is very similar to
Cortinarius imbutus, but has
much longer spores, which are more amygdaloid in shape. Both species have a
somewhat waxy to silky appearance when dry. The degree of verrucosity of the
spores tends to vary between collections. In general, the Western American
collections seem to be on the smoother side.
