The sickener, emetic russula, or vomiting russula.
Fruiting Body General Description (General Characteristics)
Russula emetica is characterized by having a red cap (pileus) in which the cuticle peels 1/3-3/4 of cap radius, a pure white stem (stipe), and a very acrid or peppery hot taste. Normal size is 5-15cm. Gills are adnexed to free. Whitish spore print. [1&2]
Cap is convex to shield the stem. Cap is red or redish in color. Cap is 3-10cm across. It later flattens or has a shallow depression. 
Stipe is 40-90 x 7-20mm, white, cylindrical, fragile. 
Spores are white to cream or yellowish. 
Flesh has a distinct or odd smell. It can be granular or brittle, slimy or sticky.
Commonly confused with Lactarius indigo, the stem of both genera typically breaks very cleanly like a piece of chalk. Lactarius exude a milky latex substance when cut into their gills and Russula do not. Russula can be easily identified by the "drop-kick" method in which the mushroom should shatter into a million pieces if properly kicked. 
- Color and size of the cap (pileus): Red Cap and 3-10cm across
- Color of the stem, including any changes in color between the bottom of the stem and the top: White stem
- Exact color of the gills: White gills which are adnexed to free
- Exact color of the spore print (ranges from pure white to cream to tan to almost yellow): White spore print
- Whether or not the cap cuticle peels, and to what extent: The cap cuticle peels 1/3-3/4 of cap radius
- Taste (acrid,mild, or bitter): Acrid to peppery hot taste 
Collection Location on GGC’s Campus
Found in the woods behind the baseball fields at Georgia Gwinnett College in Lawrenceville, GA.
All Russula species are mycorrhizal, which means they have a mutualistic association with the roots of trees, especially members of the oak family (Fagaceae) and pine family (Pinaceae). It's a common occurrence that Russulas can be found when it's very dry, and there aren't many other mushrooms around. 
Summer to late autumn.
