description Chrysothrix candelaris Overview

Chrysothrix candelaris, commonly called gold-dust lichen, is a leprose lichen with a bright yellow to yellow-green, powdery surface. It usually grows on bark and exposed wood, especially in shaded or humid woodland habitats, where its loose granules can form conspicuous patches rather than a leafy or branched body. The species is recorded in parts of the Northern Hemisphere and illustrates a lichen with a granular thallus.

help Chrysothrix candelaris FAQ

What does Chrysothrix candelaris look like?

Chrysothrix candelaris forms a bright yellow, powdery crust on its substrate. Its granular appearance distinguishes it from leafy lichens with visible lobes.

Where does Chrysothrix candelaris grow?

It is commonly found on nutrient-rich tree bark across the Northern Hemisphere. The species is associated with bark surfaces rather than the exposed coastal rocks used by marine lichens.

Is Chrysothrix candelaris tolerant of polluted air?

Yes, it is notable for tolerating pollution better than many lichen species. That tolerance helps explain why it can persist on urban or nutrient-enriched bark.

Is Chrysothrix candelaris a crustose lichen?

Yes. Its thallus is powdery and crust-like, with the growth closely attached to the bark instead of forming hanging branches or broad leafy lobes.
