Coccora

MODERATE

Amanita calyptroderma

Overview

Growing next to north parking lot at Lake Temescal. Growing near at least 2 death caps, the yellow cap color on this one leads me to think this is some other Amanita species but I'm not sure which. It was about the size of a tennis ball and might have grown to a pretty large size, so I feel kind of bad about disposing of it, but there were a ton of people nearby and obviously don't want a dog or a kid eating it in case it is toxic
