Emerging Ferns are so Intricate and Detailed

Below is a set of photos from a recent trip to the woods, all ferns in the wild with their fiddleheads unfurling (for lack of a better word) ... so intricate and full of details. All of this season's fronds are wrapped up inside the fiddlehead.

I read a few introductory pages of the "Peterson Field Guide to the Ferns".  I found it rather amazing that worldwide there are about 10,000 species of ferns covering almost all ecosystems. This includes mountains and swamps; in sunny open fields and dimly lit wet crevices; on high, dry windy cliffs and on still waters of ponds and lakes; in the Arctic and Antarctic Circles (though sparingly) and tropical jungles (in great quantities). The only exception seems to be desert ecosystems.

Unfortunately all I know about the images below is that they are ferns.  I have no idea what specie(s) is/are represented here.

All photos were shot with the Panasonic GX80/85 and Olympus 60mm macro.
