Ravenal's stinkhorn (Phallus ravenelii) growing in the front yard. Each stock only lasts a day. It really stinks and so attracts the flies very effectively.
These little mushrooms (below) are getting the only few minutes of sunlight they get each morning, as they are ensconced in a deep groove on the side of a rotting log. They're about 1/2 inch tall.
