Family in the spotlight

Found this little family of fungi huddled together, growing in mulch, in the same area that I photographed the amazing Stinkhorns recently. I've no idea what kind of mushrooms these are, but I love the way they develop cracks and wrinkles as they get older - kind of sounds familiar, ha! Now, they are all just piles of dead caps and stalks, unfortunately.

Any chance these might be Cracked-Cap Mushroom / Agrocybe dura?
