Amanita

Yellow Orange Fly Agarics Fruiting

The Yellow Orange Fly Agaric (Amanita muscaria var. formosa) is common in New England, especially where conifers grow.  Out West this mushroom is often a bright red color, but in the East it’s typically orange/yellow. 

When certain gilled mushrooms, including many Amanita species, first form they are encased in a membrane called a “universal veil.”  As the mushroom enlarges and matures, the veil ruptures, with remnants of it remaining on the mushroom’s cap.  Fly Agaric fungi got their name from the custom of placing little pieces of the mushroom in milk to attract flies.  The flies supposedly become inebriated and crash into walls and die.  This mushroom is somewhat poisonous (as are many Amanita species) and hallucinogenic when consumed by humans.  The toxins affect the part of the brain that is responsible for fear, turning off the fear emotion.  Vikings, who had a reputation for fierceness, are said to have ingested this mushroom prior to invading a village.

American Caesar’s Mushroom Fruiting

8-12-15 American Caesar's MushroomAmerican Caesar’s Mushroom (Amanita jacksonii), a member of the Amanita genus, 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.
