Pleopeltis polypodioides (syn. Polypodium polypodioides), known as the resurrection fern, is a species of creeping, coarse-textured fern native to North America.
When the fronds "dry", they curl with their bottom sides upwards so they can rehydrate quickly when rain comes, as most of the water is absorbed on the underside of the leaf blades. They lose around around three quarters of their free water in dry spells, sometimes up to 97% without losing the ability to revive.
Not a parasite but it does tend to grow on ancient limbs.

I planted Resurrection Fern with Christmas Cactus and a Bromeliad in a grapevine ball a couple of years ago. I was not successful in keeping the environment moist enough indoors for the fern to thrive.
This clump has grown on an old dinner plate for years, outdoors.
Resurrection fern earned the title of `first fern in space’ when it traveled aboard the Space Shuttle Discovery in 1997. The fern was taken into space to observe its resurrection at zero gravity and the results showed that the fern was able to complete this process without gravity.
