## Appearance

The Star Moss is a small, cushion-forming plant, typically bright green to olive-green when wet, but often reddish-brown and crisp when dry. Its tiny, star-shaped leaves unfurl when hydrated, giving it a distinctive fuzzy appearance. It forms low-lying mats or dense tufts.

## Taxonomy

- **Kingdom:** Plantae
- **Phylum:** Bryophyta
- **Class:** Bryopsida
- **Order:** Pottiales
- **Family:** Pottiaceae
- **Genus:** Syntrichia

## Interesting facts

- It can live for hundreds of years, slowly growing into ancient, green cushions!
- Star Moss helps clean the air by trapping dust and tiny particles!
- Star Moss is one of the toughest plants, even surviving in outer space experiments!
- This moss has tiny leaves that curl up tightly when dry, like a sleeping star!

## Special abilities

- **Drought Resurrector:** Star Moss can completely dry out and appear dead, only to rehydrate and revive within minutes of receiving water.
- **UV Shield:** Star Moss has special pigments that protect it from harsh sunlight, allowing it to thrive in exposed, sunny spots.
- **Water Sponge:** Star Moss can absorb many times its weight in water, helping to store moisture in dry environments.

## Measurements & details

- **Height:** 1-5 cm
- **Spread:** 5-15 cm
- **Edible:** No
- **Toxicity:** None
- **Lifecycle:** Perennial
- **Pollination Method:** Wind

## Ecological connections

- **Shelter:** Tardigrade (*Ramazzottius varieornatus*) — Tiny 'water bears' live in the water film on moss.
- **Shelter:** Springtail (*Orchesella cincta*) — Small insects find homes and moisture within moss cushions.
- **Symbiotic with:** Potworm (*Enchytraeus albidus*) — Tiny worms help decompose organic matter within the moss.
