I went out to take some more pictures of my pink cactus because I liked the design on the top of the cactus. While there I looked in another one of my planters and noticed a fungus in the soil. I did some investigating and identified it as Bird Nest Fungi. I had never seen anything like it before. The photo of the little round brown and white buds are pre the birds nest. The dark colored cups are the birds nest. You can see the little eggs inside the cups.
