I spotted all three of these fungi just a few yards (meters) apart from the boardwalk crossing a swamp.
The first one struck me as a great spot for a bird or insect to perch although I don’t know how securely it is attached to the tree and no obliging subjects came along to test it out.

The next one was much more delicate, and also could serve as a perch but I suspect it wouldn’t hold up to much weight.

This final group was on a tree facing the one just above, looking like auditorium seating for a performance.
