Answer

**Step-by-Step Solution:**

1. **Understanding Bryophytes**: Begin by recognizing that bryophytes are non-vascular plants that typically grow in moist environments. They are divided into three main groups: liverworts, hornworts, and mosses.

2. **Analyzing the Options**: The question provides four options: Vuxbomia, Dawsonia, Fontinalis, and Xerpsis. We need to determine which of these is the smallest bryophyte.

3. **Evaluating Each Option**:
- **Vuxbomia**: This option is not widely recognized as a bryophyte, and further research indicates it is not the smallest.
- **Dawsonia**: This is known as one of the tallest bryophytes, with heights ranging from 50 to 70 cm, so it cannot be the answer.
- **Fontinalis**: This is a type of moss, but it is not the smallest bryophyte either.
- **Xerpsis**: This option is known to be the smallest bryophyte, with a height of approximately 5 mm.

4. **Conclusion**: After evaluating all the options, the smallest bryophyte is **Xerpsis**.

**Final Answer**: The smallest bryophyte is **Xerpsis**.
