Wow! Never seen anything like that before. It looks like you might have sporangia born on the abaxial surface of a false indusium. The only genus known to do that is Adiantum. The blackish lustrous rachises and flabellate pinnae support this idea as well. So, perhaps it is a cultivar of Adiantum raddianum or A. capillus-veneris.
Thanks for the answer! I also believe that this is Adiantum, but I searched the entire Internet and nowhere found anything similar in structure. Although I had suspicions of Hymenophyllaceae, but there the plants are more delicate, this plant is still tough, dense.

I just updated the post with and identification of the species and cultivar provided by Layne Huiet. Great plant!
Thank you! Now he is not nameless, and it is clear what care requirements he needs.
