Cortinarius talimultiformis is fairly typical of /Multiformes in the yellow-brown cap, relatively squat stature, white to grey-white young gills and white context. The species in this section are easy to recognize as a group but hard to differentiate to species. The description notes that fibrils on the pileus and margin are typical of this species, but I have observed fibrils on the margins of C.multiformis collections so am not yet clear how to use this feature in differentiation. While the type description differentiates Cortinarius talus (deciduous forest) from Cortinarius talimultiformes (Picea and Abies) on the basis of habitat, in our region Cortinarius talus is found in conifer forest too.
