You may think you are a badass. You will never be as badass as Tail gunner Lawrence Benner, on a Lancaster bomber, Royal Canadian Air Force, 1943. Respect
Xylaria polymorpha, commonly known as dead man's fingers, is a saprobic fungus growing from the bases of rotting tree stumps and decaying wood. It has elongated upright stromata poking up through the ground, much like fingers or toes.
This one is freaky! I promise there is no yellow in the photo. I was skeptical, (as always) and opened the file in Photoshop. I "zoomed in" and used the color picker tool to investigate. The area that appears yellow really does go from 255-255-255 (total white) to 0-0-0 or solid black. Because of the low resolution of the file there are areas that are still equal numbers, so neural color, very slightly off pure white and slightly off pure black, but not a hint of yellow.
Just freaky, our brains make it look yellow, and it simply is not.
