I have a sprig of fern that has no spores on the underside of its leaves, but has a reddish-brown process coming out the top of them stem that's covered with small reddish brown spheres. It's been living in a cup of tap water since November of last year.

Does anyone know how I would go about trying to plant this?

I haven't seen anything like it since, so it would be great to see if I can keep it alive and get it growing.

Thanks!
