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
Thrives in full sun to partial shade. At least 4–6 hours of direct sunlight encourages strong growth and flowering. Tolerates light shade near water edges.
Temperature
Hardy in temperate climates, tolerating temperatures from -20°C to 30°C. Dies back in winter in cold regions but regrows from rootstock in spring.
Nutrient
Benefits from nutrient-rich water or occasional aquatic fertilizer. Naturally thrives in fertile, silty pond margins where organic matter accumulates.
Soil
Grows best in rich, muddy, or silty substrates in shallow water. Tolerates a range of soil types as long as moisture is constant. Thrives in nutrient-rich pond margins.
Maintenance
Low maintenance. Remove spent flower stalks and yellowing leaves to keep plants tidy. May spread vigorously; thin colonies periodically to prevent overcrowding.
Water
Aquatic to semi-aquatic; requires consistently wet or submerged conditions. Grows in shallow standing water, pond margins, or saturated soils. Do not allow to dry out.

Seasonal Behavior
Spring
New leaves emerge from the rootstock in spring as water warms. Rosettes of basal foliage develop rapidly in shallow water or wet mud.
Autumn
Seeds mature and drop into the water or mud in autumn. Foliage begins to yellow and die back as temperatures decline.
Winter
Dormant in winter, with foliage dying back completely in cold climates. Survives as a submerged rootstock, regrowing vigorously in spring.
Summer
Flowering occurs in summer, with tall, branched stalks bearing numerous small white to pale pink flowers. Attracts pollinators and provides habitat for aquatic wildlife.
