Brown spots on java fern....critters?

I have noticed that I have brown spots on the undersides of my java ferns. It is usually on the underside of each rib, but not always. When I look really close, they sort of look like clusters of brown eggs, but I have never seen any critters in my java jungle. I have looked pretty closely and removed a bunch of my java ferns for inspection, but I still don't see any critters in there. Does anyone know what this might be? The older leaves all seem to have them, but the newer leaves rarely do. They are not fish eggs though, that I am sure of. There are no breeding fish in that tank. I will post a pic as soon as my girlfriend shows up and tells me where she put her digital camera.

I believe that is how the plant propagates.... like little buds..

Poohbee is correct, if Java Ferns are actually ferns. The small clusters are most likely spores especially if they occur in rows or other orderly fashions. Look up "fern spores" on google and you'll find some pick to compare to (though most won't be aquatic species)

Somebody set us up the tank!

It's a fern...those are sori. So the spores will eventually come out of them. If they get fertilized within their little "house" then they will spit out the typical java fern babies. Its quite an interesting little twist to the taxonomic group

Re-boot!

So, what you guys are saying is that all java ferns have little brown dots on their undersides? I saw the same thing at the LFS where I buy my ferns from when I went back there, but I have seen java ferns in other tanks that didn't have anything of the sort. Does anyone have a picture of these?

Take it from me, they are all correct. I have about 5 medium sized java ferns, and about 4 of them got the spots that you are talking about. Now there are probably about 100 plantlets growing on top of the bigger ferns. Eventually they break off and grab onto something and get bigger from there. I have little plantlets all over the place now.

Hmm.... those look kind of gross, like some sort of critter infestation. Geez, I never see those in Amanos pictures. Maybe I will switch to a different plant that doesn't make my skin crawl, like Anubias.
