This is not a wig on the forest floor - it just Resembles one

Delicate strands of extraordinarily thin ice grow out of rotting tree branches like hairs on a head. The ephemeral hair ice can last for only a few hours to a few days if the temperature stays freezing. Researchers have known since 2005 that cold-tolerant fungi are responsible for the tufts of ice, but only recently uncovered the species responsible for the ice growth, the chemical composition of the melted hair ice, and just how the fungi stimulate the unique ice growth. It was first described almost 100 years ago in 1918 by geophysicist and meteorologist Alfred Wegener (who is famous for originating the theory of continental drift in 1912). At that time, he proposed that the unusual ice formation was probably due to fungus growing on the damp and decomposing wood.
