I spotted this mushroom on my morning walk with Spencer, but the latticework cap hadn't opened yet. I see at least one of these every year and knew it was a matter of minutes before the basket structure was going to open. I returned about half an hour later with the camera and this is how it looked. It's called Basket Stinkhorn and it really does have a foul smell. The internet tells me the smell is to attract insects that help distribute the spores. 24 hours later the basket structure and most of the cap was gone. What was left was laying on the ground. It was about seven inches tall.
