Lunularia cruciata thallus is pale glossy green with undulate margins and crescent-shaped cavities containing vegetative propagules (gemmae). The dorsal surface of the thallus is divided into polygonal areas each with an air pore. The ventral surface bears rows of hyaline scales to each side of the median line.
Widespread in New Zealand on moist soil in open forest, beside streams and as a troublesome weed of greenhouses and shaded gardens.
