It is possibly Blechnum schomburgkii (Klotzsch) C. Chr., common found at the high altitude grasslands in southeastern Brazil. It has pale (castaneous) scales at the basal petiole. In B. brasiliensis they are darker (blackish).
Thanks for the suggestion. I bet you are correct. Next time I’m in the same area I’ll collect it.
