  • Photo of Amanita flavoconia (Amanita flavoconias)

Phonetic Spelling:am-ah-NEE-tah flah-voh-KOH-nee-ah

Genus:Amanita

Species:flavoconia

Family:Amanitaceae

The Amanita species is frequently encountered in the Midwest and Eastern regions of North America. These mushrooms typically emerge during early to mid-summer in forested areas or natural landscapes. They can be found either alone or in scattered groups, primarily beneath hardwood trees, particularly oaks, and occasionally under pines. The mycelium of these fungi forms a symbiotic relationship with the roots of nearby host plants, known as an ectomycorrhizal association.

This species is believed to be toxic and is closely related to other harmful Amanita varieties, making it advisable to steer clear of them. The cap ranges from orange to yellow-orange, is sticky, and features yellow warts, measuring up to 4 inches in diameter. The gills are densely packed, white, and do not attach to the stalk. The stalk itself is pale yellow to white, with a swollen, oval base and a powdery texture. A persistent white annulus is situated near the top of the stalk, while the volva is yellow, delicate, and often remains in the soil after the mushroom is harvested. The spore print is white.

The most notable characteristic of this mushroom is found at the base of the stem, where the universal veil breaks apart, leaving behind yellow remnants.
