Backyard and Beyond

Common Bird’s Nest Fungi (Crucibulum laeve), sometimes also known as White Egg Bird’s Nest fungi. The English muffin form (upper left above) is the early stage. Not sure how it loses its top, but then the “nest” is exposed with the “eggs” or fruiting bodies, as in the lower right.
These were growing on what I presume is coir, woven in mats and used to protect slopes. It rots into the bank, and clearly the fungi are helping it rot.
This is Dung-loving Bird’s Nest (Cyathus stercoreus).
Prolific in a richly-mulched planting area.
