Witch's hat

Hygrocybe conica

A species of Waxcaps. Also known as Blackening waxcap, Blackening waxy-cap.

Following summer and autumn rains, you can spot Witch's hat mushrooms emerging in clusters across various landscapes like fields, grasslands, and roadsides, often thriving in areas with poor soil quality. To observe their vibrant orange or red hues, you need to find them quickly, as their caps rapidly transition to a deep black. These mushrooms then stand for several weeks, maintaining their glossy, dignified appearance. It's important to note that the Witch's hat is considered poisonous.
