Cortinarius corrugatus Peck 1872
This cort is relatively common in our region and is also one of the easiest corts to identify because of its distinctively corrugated cap. It is somewhat viscid or tacky to the touch, is conic to campanulate prior to expanding and bears a knob at the comparatively smooth and more deeply colored central disc of its ochre-brown cap. The gills are pale violet at first, becoming brownish with maturity. The cortina is brownish. Spore print is reddish-brown. The whitish stipe exhibits fibrilsand is orange-brown toward the enlarged base. These appear from July to September and are mycorrhizal with broad-leaf trees, especially oak. Not edible.
This is in the Cortinariceae family of the Agaricales order.
