Perfect camo

Here is a before and after of my favorite mushroom. Before, it blends in with the dirt in my front flowerbed. After being stepped on, it looks like ordinary dirt. Note the treadmarks from my shoe.

Ever the curious person, I looked up mushrooms and toadstools. Apparently, the difference lies mostly in edibility.

According to the American Heritage Dictionary, a toadstool is an inedible fungus with an umbrella-shaped fruiting body. Conversely, a mushroom is any of various fleshy fungi of the class Basidiomycetes, characteristically having an umbrella-shaped cap borne on a stalk, esp. any of the edible varieties.

I could look this up in the “National Audubon Society Field Guide to North American Mushrooms.” I'm assuming this was written by mycologists -- botanists who are experts in fungus amungus.

Are there any mycologists out there who can identify this specimen? All I know is that I’m not eating any wild mushrooms – or toadstools.
