Ferns are considered a more ancient and primitive group than flowering plants.
Their method of reproduction involves releasing millions of tiny spores into the atmosphere.
Fern spores tend to be
larger than fungal spores but smaller than most seeds.
My first impression upon seeing these spores is that they look like detached lobster tails.
They certainly look impessive at 400 power. As for what type of fern this is, I haven't got a clue.
I got the specimen premounted so I don't even know what the fern itself looks like.
