When you see a scene like this you tend to want to sit down and just watch quietly to see when the pixies and fairies arrive.
These are Sulphur Tuft mushrooms. They normally grow on dead hardwood trees and can be up to 70 millimetres in diameter. The stems are 50 - 200 x 2 - 10 millimetres and join to other stems at the base. These I also photographed at Sleepy Hollow.
