Masonhalea richardsonii, known as Richardson's masonhalea lichen or the arctic tumbleweed, is a fruticose lichen found mainly in Northern ecosystems.

It is known as the arctic tumbleweed because when dry, it curls up and is spread by wind across the open tundra.

[1] It has a unique brown colouration with white netting patterns.
