Phonetic Spelling:am-ah-NEE-tah gem-MAY-tah

Genus:Amanita

Species:gemmata

Family:Amanitaceae

This species bears resemblance to Amanita muscaria, A. pantherina, and A. cothurnata, and it seems to hybridize with them. While these species can be found in North Carolina, they appear to be less prevalent than A. gemmata and A. muscaria.

The cap exhibits a dull yellow to pinkish-yellow hue, adorned with small to medium-sized white scales or warts. It may be flat or feature a slight depression at the center, where the color tends to be a bit darker.

The gills are white, closely spaced, and slightly attached to the stem.

The stalk is white, characterized by a bulbous base and a prominent collar. It gradually narrows, initially being solid before becoming hollow, and is marked by cracked, scaly bands.

The annulus is white and delicate, often fading with age, positioned near the top of the stalk.

The spore print is white.

These mushrooms typically thrive in forests or other natural settings, and can also be found in landscaped areas. They may grow individually or in small clusters within mixed hardwood-conifer forests or in pure pine stands. Their growth season begins in late spring or early summer and continues into the fall.
