Agrestia J.W. Thomson
Commonly known as
Agrestia Lichen
Agrestia J.W. Thomson is a genus of small, squamulose lichens in the Megasporaceae family, occurring primarily on calcareous soils and rocks in arid and semi-arid grasslands of western North America.

Identification & Classification
Color & Surface
Vibrant "highlighter yellow" scales. They turn greenish when wet because the yellow skin becomes see-through, revealing the green algae inside.
Shape & Form
A scaly "crust" made of tiny, flat tiles. It grows in irregular patches that look like cracked paint or a tiled floor on the ground.
Fruiting
Small, sunken black or reddish dots in the center of the scales. These act like "launch pads" to release the lichen's spores.
Growth Habitat & Substrate
Strictly soil-dwelling in dry areas. It grows on dirt or among mosses. Pro tip: if it's on a bare rock, it's a different species.

Care Requirements
Sunlight
Prefers partial shade to full sun, typically found on soil or mosses in open habitats.
Temperature
Thrives in cool to mild temperatures, ideally between 8–18°C.
Nutrient
Does not require fertilization; nutrients are absorbed from rainwater and decaying matter.
Soil
Grows best on acidic, well-drained soils with organic matter.
Maintenance
Low-maintenance; remove debris gently and avoid trampling.
Water
Requires moderate moisture; tolerates brief dry periods but prefers consistent humidity.

Seasonal Behavior
Spring
Spring triggers active growth and spore production.
Autumn
Growth slows in autumn as temperatures drop; lichen remains green but less active.
Winter
Dormant in winter, surviving cold by reducing metabolic activity.
Summer
May become dormant during summer droughts, reviving with moisture.
