What are the brown spots on the back side of a fern? Is it how they reproduce? Are they bugs? Whatever they are, they keep me from touching them :(
I'm pretty sure they're spores (though I don't know a whole lot about ferns.)
definatly spores. its how they reproduce.
There's two phases to fern reproduction, though the precise madness to this archaic beast eludes me. Try googling it if you want to know more :p
Spores. They just kinda drop from the bottom of the leaf and do their thing on the ground.
