Description
The cap of Russula mordax is variable, and can be reddish, orangish, yellowish, or brownish. It is about 4-10 centimeters in diameter. It starts out convex and becomes broadly convex, flat, or depressed as the mushroom gets older.[2] The gills are cream-colored[1] and adnexed.[1] The stipe is about 8 centimeters long and 3 centimeters wide. It is white and often has red splotching on the lower part.[3] The spore print is yellowish ochre. This mushroom has a strong acrid taste,[2] and may be poisonous.[1]
Habitat and ecology
Russula mordax is mycorrhizal. It is found in under western hemlock and douglas fir in coniferous forests.[1]
