Russula sp-IN75 is a small mycorrhizal mushroom that can be found in woodland settings in the summer. This one was found growing from woodland soil near Black Oak, Bur Oak, Elm, Northern Red Oak and Shagbark Hickory at Indian Cave State Park in southeastern Nebraska. It was found fruiting scattered in a small group.

The cap is bright red with color fading toward the cap margin becoming depressed or upturned with age. The gills are white to cream-colored. The stem is cream-colored with pinkish hues. The taste is distinctively peppery/spicy (acrid).
