These mushrooms look like they are at the very end of their life cycle. The ones I studied last year in October ended up this way, with their caps curling up and turning sticky. To identify them I'd look for something similar in shape, slightly larger and much lighter in color.
Your photo provides good depth to see how they compare to their surroundings. I admire how sharp the frothy greens are underneath them. I'm reminded of the woven rice leaf hats worn in Southeast Asia by the shape of the mushrooms. I like the photo very much.
