Distribution: Broad
Habitat: All variety of forests with both conifers and hardwoods
Conservation Status: Not of concern
Russula crenulata, R. raoultii, and R. cremoricolor are three very similar species that cannot be confidently separated by macroscopic features, and not easily even with microscopic features. All are medium-sized, with whitish to pale yellowish to yellow caps, white spores, and acrid taste, and all grow in a variety of forests with both conifers and hardwoods. R. crenulata has the largest spores (8-10.5 x 6.5-7.5 um), numerous cystidia in the cap cuticle, a cap cuticle that pulls away easily at least halfway to the center, and finely serrated gill edges (often need a handles to see clearly). R. raoultii has the smallest spores (5.7-9 x 5.5-7.5 um), best developed network of spore ornamentation, less numerous cystidia in teh cap cuticle, and moderately peelable cap. R. cremoricolor has mid-sized spores (7.5-9.5 x 5.7-8 um) and less prominent spore ornamentation, and lacks partial gills between the full gills.
