Russula crenulata

Distribution: Broad

Habitat: All variety of forests with both conifers and hardwoods

Conservation Status: Not of concern

Identification Notes:

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.
