Cortinarius comptulus M.M. Moser, Nova Hedwigia 14: 514 (1968) [MB#329015] A Cortinarius in Telamonia, section Rubricosi. Described from Europe by Moser, it is known from Alaska and Oregon, and likely occurs elsewhere in the Pacific Northwest. Copyright Noah Siegel: NS1830
Cortinarius armeniacus is not often collected in our region, but is likely overlooked due to inconspicuous colors and general neglect of Cortinarius species. It can be recognized by the smooth to shiny, hygrophanous yellow to chestnut-brown cap with white margin, firm whitish-drab stipe and convex cap with low umbo
Cortinarius fructuodorus is best recognized by the Cortinarius traganus-like fruity pear odor for which it is named, overall brown (or slightly purple-brown tones) and spores in the range of 8.5-10 x 5.0-6.0 microns. This species is one of several larger pale Telamonia in our region which need further study.
Cortinarius sordidemaculatus means "dirty / sordid" "spotted". It is recognized by the fibrilose dark brown cap, medium size, lack of violet tones with dark black-brown spots and bruising.

Cortinarius traganus (Fr.) Fr., Epicrisis Systematis Mycologici: 281 (1838) [MB#164677] Description: Cap 40 - 90 mm wide, hemispherical when young, then convex to plane, surface dry, tomentose, often cracked and scaled with age, lilac when young, fading to lilac-grey or pallid brown, gills ochre when young, darkening to rust brown, never lilac or purple toned,...

Cortinarius laniger Fr., Epicrisis Systematis Mycologici: 292 (1838) The ITS region is the standard for Cortinarius phylogeny and species deliniation. However, there are known areas where species that appear morphologically distinct show slight ITS variation - below the typically accepted threshold of 99% (established in Garnica et al 2016). The case of Cortinarius laniger, solis-occasus... Continue Reading →
