yep, they're mushrooms. i'm no mycothingy, but we're in hardwood forest, mostly maple, and they're
growing in more open areas, like along our driveway. they're popping up through pretty hard ground, which is amazing because they're so fragile when you touch them! they're kinda long, then they open up like an umbrella as they age, then they turn all slimey and black like primordial ooze (which of course the dogs paws gravitate to). i guess you have to catch them when they're really fresh. finally going to try some tonight, we'll see how they taste!
