Possibly Stinkhorn? Found this while mowing the grass (South Central US). Initial searching says it's a type of Stinkhorn, and it reeks to high heaven, so I'm inclined to believe that's what it is. However, all the pictures I'm seeing of Stinkhorn are smooth and round, while this has very distinct ridges. Any thoughts? Originally by u/chicken-cuddle on Reddit: https://tinyurl.com/2a8r44qx
