Introduction
Mosses are some of the most fascinating and underappreciated plants on Earth. One particularly intriguing species is Donnellia lageniformis (Müll.Hal.) W.R.Buck, also known simply as Donnellia moss. This charming little moss belongs to the Sematophyllaceae family and has some unique characteristics that make it stand out. Let’s take a closer look at this marvelous moss!
Background on Bryophytes
Before diving into the details of Donnellia moss, it’s helpful to understand a bit about mosses in general. Mosses are non-vascular plants in the division Bryophyta. They lack true roots, stems, and leaves like other land plants. Instead, they have rhizoids that anchor them and absorb water and nutrients. Mosses reproduce via spores rather than seeds and are found in diverse habitats worldwide, from arctic tundra to tropical rainforests.

Morphology and Identification
Donnellia lageniformis is a small pleurocarpous moss, meaning it has a branching, feather-like growth form. Its scientific name comes from its flask-shaped (lageniform) leaves. The leaves are concave and tightly imbricate (overlapping), giving the moss a very neat and tidy appearance. Donnellia has a glossy sheen that helps it stand out from other mosses.

The stems of Donnellia are creeping and freely branched. It produces short, erect fertile branches with the sporophytes (spore-producing structures). The

seta (stalk) is smooth and reddish, while the capsules are inclined to horizontal and have a peristome (toothed opening). These traits help with identification.
Global Distribution and Habitat
D. lageniformis

has a wide distribution across the Americas. It is found from southern North America through Central America and the Caribbean to South America. This adaptable moss grows on various substrates, including tree bark, decaying logs, rocks, and soil banks. It seems to prefer humid, shady sites in lowland to montane forests.
Ecological Roles and Adaptations
Like other mosses, Donnellia plays important roles in its ecosystems:
- Helps retain moisture and prevent erosion
- Provides shelter and food for micro-organisms and invertebrates
- Contributes to nutrient cycling and soil formation

- Acts as a bioindicator of air and water quality
Donnellia has several adaptations that allow it to thrive:
- Concave, tightly packed leaves help conserve moisture
- Rhizoids anchor it to substrates and absorb water/nutrients
- Spores allow long-distance dispersal to new habitats
- Clonal growth enables local spread and persistence
