Mycology Report

Mycology is the biological study of fungi - YEAH. I love to eat fungi - otherwise known as mushrooms. Unfotunately I don't think the ones growing in my yard are edible; too bad because there are lots of them and they keep gettin' bigger. Here's a ring of mushrooms - Todd says it's a fairy ring - what? Look it up on Wikipedia - it's kind of cool.

These were big several days ago, now even bigger.

This one looks like a different type, it was growing in the grass.

This one looks like a giant, yet slimey, pearl - pretty cool. Can anyone tell me what kind these are and if poisonous?
