Comments. This telamonioid fungus looks like Cortinarius xenosma Soop, but without the typical reddish tinge on the stipe. It also deviates by being more slender in average habit, and by the brick-coloured lamellae. Available molecular data show that the two species aregenetically remote, placing C. xenosmatoides near several dermocyboid species, such as Cortinarius cardinalis (E. Horak) G. Garnier and Cortinarius canarius (E. Horak) Gasparini. This is remarkable, since it is a definitely telamonioid species, apparently lacking in anthraquinonic pigments as witnessed by the absent alkaline reaction.
