Cortinarius rubellus is a small to medium-sized mushroom with a reddish-brown cap and white to pale yellow gills. It has a slender stem and can grow up to 6 cm tall. In East and Central Texas, it typically fruits in the fall, often in association with coniferous or deciduous trees, particularly pine and oak. The fungus is considered poisonous and contains orellanine, a toxin that can cause kidney damage if ingested. It has been found in various regions of East and Central Texas, including the Piney Woods and the Edwards Plateau.

Underside of deadly webcap mushrooms (Cortinarius rubellus(?)) collected at mushroom walk of Gulf States Mycological Society. Little Thicket Nature Sanctuary, Cleveland, Texas, November 13, 2021San Jacinto County, Texas, United StatesObservations of Cortinarius rubellus in East and Central Texas were made during mushroom walks organized by the Gulf States Mycological Society. On November 3, 2018, brown webcap mushrooms, possibly Cortinarius rubellus, were found under oaks in Little Thicket Nature Sanctuary, Cleveland, Texas. The gills of these mushrooms were also observed and documented. Similar observations were made on November 13, 2021, with the collection of deadly webcap mushrooms, potentially Cortinarius rubellus, at the same location. The underside and gills of these mushrooms were also examined and recorded. All observations suggest that Cortinarius rubellus may be present in East and Central Texas, specifically in the Little Thicket Nature Sanctuary, and can be found under oak trees. Further identification is needed to confirm the species. The fungus was observed on two separate occasions, three years apart.
