(Underwood's Spikemoss)

Selaginella underwoodii looks alot like moss growing over a rock. The best clue to the true identity of Selaginella are the sporangia in the leaf axils of the fertile fronds. Selaginella underwoodii also has bristles prominently visible at the ends of the leaves. In addition, the lamina of a moss leaf is usually one cell thick while the leaf of Selaginella is many cells thick.
