Welcome to the wonderful and often wacky world of mushrooms - thousands of varieties, flavors and colors and all proudly displayed in this great post by Webecoist.
Turkey Tail Mushrooms, Bleeding Tooth Fungus and the Bearded Tooth Mushroom make up this list of strange and exotic fungus.
The post gives some great insight in to each mushroom listed, where they originate, what they look like and whether or not they're edible. It seems that the ones that look the most appetizing are usually the most deadly.
