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.
