This mushroom has been on my "list" for some time and this weekend I finally found a tree sporting a bunch in great shape. This is Armillaria mellea also known as the Honey Mushroom. It is a parasitic mushroom and often times will kill it's host tree. They are normally seen growing on the ground around the base of the tree but this group I found was several feet up from the base. An indicator of this mushroom is the persistent ring that is still on the stem at maturity. The books list the taste as mild to bitter so I will soon find out if this is as edible as I have been told.
Once again.... enough butter, salt and pepper would make even mud taste good. Or so I've been told.
