Answer: Mario was right! A. Muscaria are toxic and hallucinogenic.
The Amanita muscaria mushroom primarily grows in woodland areas in leaf litter. The color of the mature cap (pileus) ranges from a striking red to yellow or orange. The cap is noted for having scattered “flakes” (scales) on the top surface, which are remnants of its protective covering (veil or volva) that it grows through its maturing process. In the mature mushroom, these scales can appear to be in concentric circles. Although not seen in this image, the stem (stipe) would have a skirt (ring) of tissue around it and have a rough appearance at the bottom third. Under the cap, this species has laminae-free white gills and white spores.1
