I found these all over the Santa Rosa Rural Cemetery last week, before we had several days and inches of rain. These slime molds are called Leocarpus fragilis. When they first fruit on decomposing plant material the little egg-shaped fungi are neon orange and nearly impossible to miss in the woods. As they mature the dry out and become burnt orange then basic brown. Eventually they burst open and release their spores. In the past I've tried to collect fresh ones but they disintegrate into a puddle of neon orange goo when disturbed so it was fun to find them dried out and easy to transport.
