Virginia chain fern looks roughly similar to cinnamon fern, which is more common in Connecticut. To identify Virginia chain fern, look for the distinctive sori (see second photo below). If sori aren't present, look for dark shiny petioles (leaf stalks).

Underside of a frond, showing the tan sori (spore-bearing structures), which form a double row outlining the major veins.
The undersides of the sterile fronds (those without sori) have an interesting (and rather attractive) pattern of veins. This is shown below in close-up.
