What in the world is growing in my garden?

What is this?! It seems to start off as a yellowy-brownish color and turn white the next day. There are about 8 patches like this in the garden.
What is that?! It certainly doesn't look healthy! Thanks to anyone who can help identify it! ETA: Thanks everyone! I'm glad to find out it's harmless. I swear, my cats will eat just about anything! ;)
