The 'black dots' (or 'brown dots') on the underside of fern fronds are reproductive structures. They are called sori(the singular is sorus). Within the sorus is a central column (columella), covered by a hard cover, the indusium (the cover you see and call the black dot). Sprouting beneath the indusium (ferns usually have indusia, but not always) and attached to the columella are sporangia, spore-bearing capsules. The fern is the spore-bearer, the sporophyte stage of the fern life cycle.
