The image shows a close-up view of several pale pinkish-white growths, which appear to be some type of slime mold or fungi.
These growths are growing on top of rotting wood and have a small white base attached to the wood. The tops of each growth are round and covered with many smaller bumps or nodes.
The growths all look similar but vary slightly in size. They range from 1/2 inch (1 cm) to about an inch (2.5 cm) across, with some being bigger on top than others.
There is a small yellowish object visible under one of the larger growths at the bottom right of the image.
The background of the image is mostly filled by the rotting wood, which has been covered with moss or other green vegetation. – AI vision
