Craterellus fallax, black trumpet. I find the dark color of these to be striking! They are widely distributed, but apparently difficult to spot and like to grow beneath oaks through mycorrhizal relationships. It seems that black trumpet is also very fragrant! I'm not sure what they smell like, but how strange to spot a mushroom on a walk because of its olfactory properties!
