Cystinarius rubiginosus, also known as Cortinarius rubiginosus, is a species of mushroom in the family Cortinariaceae.

Description

The cap of Cystinarius rubiginosus starts out campanulate or rounded. As the mushroom matures, it becomes convex or flat. It is about 3-9 centimeters in diameter, and is beige to orangish brown.[1] The gills are adnate and start out beige, before becoming orangish or brownish as the mushroom gets older.[2] The stipe is about 5-8 centimeters long, 1-3 centimeters wide, and orangish.[3] A cortina is present, and the spore print is rusty brown. While some classify it under the genus Cortinarius, it has cystidia, leading others to classify it under the genus Cystinarius.[1]

Habitat and ecology

Cystinarius rubiginosus is found in Western North America, from California to Alaska.[2] It is most often found in coastal spruce forests.[1] While it usually grows with sitka spruce, it sometimes grows with other conifers, as well as tanoak.[2]
