Paxillus involutus : Brown Roll Rim
Once considered edible for hundreds of years, the Brown Roll Rim was only known to cause upset stomachs, digestive issues, and nausea if eaten raw. However, in 1944, German mycologist Julius Schaffer died from what seems to be autoimmune hemolysis. Meaning that eating this mushroom may trigger your red blood cells to burst and release their contents even if you've eaten this mushroom plenty of times and have been fine!

Where to Find This Mushroom in the Wild?
Forming a ectomycorrhizal relationship with a wide variety of both coniferous and deciduous trees, these mushrooms are found all over the world in a majority of wooded areas due to the broad requirements for this mushroom to thrive. In fact, finding this mushroom in certain areas is indicative of a few net positive results for the host plants and trees. As of lately, researchers have used these Paxillus involutus in seedling inoculation programs as evidence suggests the benefits to the root systems of the host trees include increased resistance to pathogens (Fusarium oxysporum).
Around here in Michigan, we'll find these tucked away in the taller grass or buttressing up next to all species of trees. Don't take these for granted as research has come out the past year to suggest this little mushroom can have some big health benefits if consumed properly.
Description of the Mushroom
Cap: Depressed :( and rolls into the bottom side of the cap // hence Roll Rim
Stem / Stipe: Bare , gills almost create honeycomb like look on the stem. Coppery Pax Mushroom seems to not do this.
Gills: on hymenium and sit close to each other. Decurrent and can be pulled easily and are yellowish/brown in color.
Hymenium: Decurrent and anastomose
Spore Print: Brown
Ecology: mycorrhizal
Edibility: yes and no... has be eaten for a very long time across most of Europe and parts of the United States until Julius Schaffer died from consuming these. Even after years of consumption, you may develop gastric pains all the way to autoimmune hemolysis which can result in fatality including shock, acute respiratory failure, and disseminated intravascular coagulation (blood clotting throughout small veins in body)
Interesting Facts
In this study, eight new compounds, named furanopaxin A-F (1-6), deoxybisinvolutone (7), and coumarinvol (8) along with two known compounds were isolated from fruiting bodies of the wild mushroom Paxillus involutus (Batsch) Fr. Their structures were established based on HR-ESI-MS and 1D and 2D NMR spectroscopic data. The results of hypoglycemic assays indicated that compounds 5-8 possessed significant α-glucosidase inhibitory activities, with IC50 values ranging from 14.65 ± 1.68 to 47.55 ± 1.47 μM, and each compound could enhance glucose consumption in insulin-resistance HepG2 cells. Further analysis by molecular docking implied that compounds 5-8 could interact with the amino acid residues of α-glucosidase, supporting the hypoglycemic activity of the compounds.
