chondropsis lichen of dry rock and exposed coastal headlands
- Size
- Height: 2–5 cm
- Lifespan
- 10–50 years
- Diet
- Grows on ground, rocks, and exposed soil in open, sunny locations. Requires well-drained, acidic soils and good light. Tolerates sun, wind, and moderate drought. Prefers dry, exposed sites with thin, well-drained soils.
- Habitat
- Grows on ground, rocks, and exposed soil in open, sunny locations. Forms shrubby, branching stalks that look like a tiny dryland bush.
- Range
- Found throughout the North and South Islands on ground, rocks, and exposed soil in open, sunny locations. Most common in the South Island's dryland regions and the North Island's volcanic plateau. Also found in temperate and dry regions worldwide.
- Endemism
- Native
- Main Threats
- None significant. This species is common and widespread in dry, exposed habitats. Localised threats include habitat loss from land development, quarrying of rock outcrops, and climate change affecting soil moisture.
- Population
- Not Threatened. Chondropsis lichen is common and widespread in New Zealand, particularly in the South Island's dryland regions and the North Island's volcanic plateau. It grows on the ground, on rocks, and on exposed soil.
- Conservation Status
- Not Threatened
The one that looks like a tiny bush has a body that is pale greyish-green to olive-green, with branching, shrubby stalks that rise from the ground like a miniature forest. The stalks are thin and wiry, often reaching 2 to 5 centimetres in height. They are branching and upright, forming dense, rounded clumps that look like a tiny version of the dryland shrubs that grow nearby. It is the lichen of the miniature bush, the one that blends in with the real bushes if you do not look closely, the one that makes the ground look like it has its own forest.
What makes it special is the shape. Chondropsis lichen is one of the most shrub-like lichens in New Zealand. Its upright, branching stalks form dense, rounded clumps that look exactly like a miniature version of the surrounding vegetation. It is a master of camouflage, blending in with the dryland shrubs and grasses. You can walk right past it without noticing. It is the lichen of the hidden bush, the one that looks like it belongs in a miniature landscape, the one that rewards a closer look.
The stalks are solid and tough, not hollow like many other fruticose lichens. They are covered in tiny, white spots (pseudocyphellae) that help the lichen breathe. The surface is smooth and shiny, often with a slightly waxy texture. Under a hand lens, the white spots are visible, tiny pores scattered across the surface of the stalks.
Biologically, the chondropsis lichen is a partnership, a fungus and an alga living together. The fungus provides structure and protection. The alga provides food through photosynthesis. The chondropsis lichen is adapted to dry, sunny locations where other lichens struggle. Its shrubby shape helps it capture light and moisture.
To find chondropsis lichen is to find the tiny bush on the ground. It is pale, shrubby, and hidden, a miniature dryland forest at your feet. You can run your finger through the stalks and feel the wiry, tough texture. It is the lichen of the miniature bush, the one that looks like a tiny dryland shrub, the one that proves that the most successful camouflage is to look like everything else.
