This is how the mushrooms I was making looked like at this stage.


Pinch the edges with your fingers following an imaginary curved line - that way you will thin the edges and curve them.


Use the dresden tool to make indentations as shown in the photo. Make some indentations deeper and longer and some shallower and shorter. Use a bone tool or ball tool to make very shallow indentations here and there (whole surface of the cap). Those indentations won't be very visible at this stage, but the dusting will bring the texture out.
