I rearranged and refreshed the hugelculture beds in my garden a few days ago and found these under a half rotted log. Not sure about the white ones but the other is Sarcoscypha coccinea, commonly known as the scarlet elf cup, or the scarlet cup. A cluster of very tiny, bright red-pink-orange cup shaped mushrooms growing from rich soil and organic matter.
