Before we get into the specifics of L. pustulata, let’s cover some moss basics. Mosses are non-vascular plants in the division Bryophyta. Unlike other land plants, they lack true roots, stems, and leaves. Instead, they have rhizoids, simple stem-like and leaf-like structures. Mosses are found worldwide in a variety of habitats and play key roles in ecosystems.
