Russula cerolens, commonly known as the pocket-stalked russula^[1] or pocket-stalked brittlegill,^[2] is a species of mushroom in the family Russulaceae. Its edibility is unknown, and it may be poisonous.^[3] It grows under both hardwoods and conifers.^[2]

The cap of Russula cerolens is brownish in color and about 4-11 centimeters in diameter. It starts out round, becoming convex and eventually depressed in age.^[4] The gills start out white and become cream-colored or yellowish as the mushroom matures. They are adnexed to adnate.^[3] The stipe is about 3-8 centimeters long and 1–2.5 centimeters wide. It is white in color and often has an orange base. In older specimens, the stipe is more cream colored, often with brownish or orangish stains. The spore print is white. The mushroom has a bitter to acrid taste.^[2] It is often described as having an unpleasant odor.^[2][1][4]

Russula cerolens is found under both hardwood and conifer trees. In coastal areas, it is known to fruit in large numbers under shore pine trees. It is found throughout the Pacific Northwest.^[2] It is also found in California, where it often grows under Monterey pine trees along the coast.^[3]
