Red Sac

I thought I was photographing a bright red fungus on this decomposing oak leaf, but was amazed to discover that it is in fact the egg sac of a spider in the genus Phrurotimpus! They're also known as ant mimic or guardstone spiders.

It's quite striking, and looks a lot like a limpet. Mom was nowhere to be seen.
