The discovery of this delightful-smelling Agaricus augustus, The Prince, can get someone hooked on wild mushrooms. The Prince is a distinctive meaty, choice edible mushroom with a delightful almond odor. Agaricus augustus is in the same genus as the much more bland domesticated store-bought mushroom. This genus is a challenging one for beginners and even fairly experienced pickers make mistakes since there are many close look-alikes. I have even seen the previous species, Amanita pantherina , identified as The Prince by an experienced biologist who was not very experienced with fungi.
Spore color is very important in telling one genus of gilled mushrooms from another.
