At the risk of boring readers with a repeat post, I seem unable to come across an American Caesar’s Mushroom without photographing it and somehow justifying its worthiness as a Naturally Curious post, even in consecutive years (a practice I try to avoid). Simply put, the beauty of this non-flowering fungus rivals that of any flowering plant I can think of.
American Caesar’s Mushroom (Amanita jacksonii), a member of the Amanita genus found in New England, differs from most Amanita species in at least two ways. It is one of the few edible Amanitas (most species are poisonous, so consumption is discouraged unless an expert identifies the fungus). Secondly, unlike many other Amanita species, American Caesar’s Mushroom does not usually have any warts or patches on its cap.
The common name of this mushroom traces back to the fact that its close relative, Caesar’s Mushroom, Amanita caesarea, which grows in Italy, was a favorite of the emperors of the Roman Empire, the Caesars. Both of these species of Amanita are mycorrhizal, forming a symbiotic beneficial relationship with the roots of certain trees. Look for American Caesar’s Mushrooms under pine and oak.
