Solving the mystery of 'hair ice'

It looks like glistening angel hair pasta growing out of rotten tree branches, but scientists know it as “hair ice.” It was first identified in 1918 by Alfred Wegener, also responsible for contributing to the understanding of continental drift. Back then, he suggested there was a relation between fungi and the growth of hair ice. Recently, investigators from Germany and Switzerland have found evidence of this relation. They identified a variety of fungi, particularly Exidiopsis effusa, which were responsible for the phenomenon, Tech Times reports. Although they know hair ice grows during humid winter nights when temperatures drop slightly below 0°C, scientists hope future research might shed some light on the specific mechanism driving the growth.
