Morphology and Identification
Tortula obtusissima var. connectens has small, dense tufts of leaves that are oblong-lanceolate in shape. The leaves have a rounded to obtuse apex (hence the species name “obtusissima” meaning very obtuse). A key identifying feature is the

- Absorbs and retains moisture
- Provides shelter for small invertebrates
- Pioneers on disturbed or bare surfaces
Tortula mosses have adaptations like thick cell walls, protective pigments, and the ability to dry out and rehydrate that allow them to survive harsh conditions.
