Hello,

This is a darkfield image from a prepared microscope slide labelled
"Fern Spicules." The nominal magnification is about 100X.

I am not knowledgeable about fern reproduction other than to recognize
that this may be a gametophyte or some stage along the way.,

What are these and can anone name the species?

Thanks for the help.
