Lots of eggs on the back of a fern.
No interactions present.
the spores of the fern?
Maybe they are, they were not on all of the fern though. Some looked like they hatched/ spawned because they had grey bits sticking out.
they are spore cases of the fern, probably a Dryopteris species of fern. the spore cases may have not developed on other leaves, or may have been already fallen off or been washed off.
