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 filtered sunlight or partial shade, typically growing in open forest canopies. Tolerates some direct light but thrives in diffuse, humid conditions.
Temperature
Thrives in cool to cold climates, ideally between 0–15°C. Well-adapted to montane and boreal forests; sensitive to high heat and dry conditions.
Nutrient
Does not require fertilization. Absorbs nutrients from rainwater and atmospheric particles. Sensitive to nutrient pollution, which can alter its growth.
Soil
Does not grow in soil. Epiphytic, growing on tree bark and branches. Requires a stable host substrate in clean-air environments.
Maintenance
No maintenance required. Protect habitat from air pollution, logging, and disturbance. Sensitive to environmental changes and slow to recover from damage.
Water
Obtains moisture from fog, rain, and humid air. Requires high atmospheric humidity; does not tolerate prolonged dry conditions or arid environments.

Seasonal Behavior
Spring
Growth resumes slowly in spring as moisture and temperatures become favorable. New thallus branches extend from existing filaments.

Autumn
Active growth continues in autumn as humidity increases. Thallus may develop fruiting structures (apothecia) under favorable conditions.

Winter
Tolerates cold winter temperatures well, often remaining dormant under snow. Survives freezing conditions and resumes growth when moisture returns.

Summer
May experience slower growth in summer if conditions become warm and dry. Remains active in cool, foggy coastal or montane environments.
