Unidentified Selk mushroom

A species of yellow incandescent mushroom grew on the planet Selk. In starlight, the mushrooms emitted a golden glow and released spores that float into the sky. In darkness, the light of the spores faded away, and the mushroom shriveled and died. The alien Tichina collected the spores in a small jar and would stir water into the dust, creating paint.

Learning from her mother, Tichina used a painting stick and blew dust over her hand to create paintings on that moved a large stone and told a story of the planet's past, including Tichina and her sister Koten's mother rebelling against the Galactic Empire's occupation of Selk. After the sisters defeated the Imperial forces at their factory, the smog in the sky retreated and allowed the stars to shine down on the planet, reviving the dead mushrooms and highlighting multiple hand prints painted on the rock.
