Entoloma serrulatum

The cap of Entoloma serrulatum is dark blue in color and about 1.5-6 centimeters in diameter. It starts out broadly convex or dome-shaped and becomes flat or umbonate as the mushroom gets older. The umbo can have a depression in the center. The surface of the cap is somewhat tomentose.^[2] The gills are whitish to pinkish and adnate to decurrent.^[3] The stipe is hollow and the same color as the cap. It is bare near the base and silky near the top.^[4] The spore print is pinkish.^[2]

DNA analysis shows that Entoloma serrulatum may actually be multiple species, even in the Pacific Northwest alone.^[2]

Entoloma serrulatum is found in both grassy areas and forests.^[1] It is saprophytic.^[4][1]
