How to recognize Tetraphis pellucida: This plant grows in small clumps on stumps or sandstone rocks. It almost always has either erect capsules with 4 large teeth (unless young and covered with a calyptra or capsule cover which is reddish on top and whitish around the bottom), or a specialized cup of little green leaves at the tip of the plant with little green gemmae that look like a bit like little green flattened eggs. These gemmae let this plant reproduce asexually without two parents, since each gemma, if it falls in the right place, will grow to be a new plant. The 1-2 mm egg-shaped leaves have a single costa which does not reach the tip of the leaf. Older plants are often brownish-red, especially on rocks.

Where to find Tetraphis pellucida:  Look for this moss on rotten stumps or rocks.
