Semerþin Mushroom

The semerþin mushroom is a blue mushroom that glows in the dark. It is said to have magical properties in the native folklore, but that has been widely disproven. It is edible but tastes like pool noodles (not that I’ve tried pool noodles) and has no nutritional value. They are mostly used as decoration.
