About Cortinarius uliginosus Berk.
The cap of Cortinarius uliginosus is orangish, and may also be ochre or reddish in color. It measures between 1.5 and 4.5 centimeters in diameter. When young, the cap is conical or bell-shaped (campanulate), and it expands to become convex, flat, or umbonate as it matures. The gills are adnate (attached flat to the stipe); they start out yellow, then turn orangish or brownish as the mushroom ages. The stipe is 2.5 to 7.5 centimeters long and 2 to 8 millimeters wide, and it is yellowish in color. A cobweb-like partial veil called a cortina is present on the stipe. The spore print of this species is rusty brown. In terms of habitat and ecology, Cortinarius uliginosus grows mycorrhizally, found under willow trees in wet locations, and also in alder carr forests. It occurs across both North America and Europe.
