Hair Ice is a rare and fleeting phenomenon, spotted mainly in broadleaf forests at latitudes between 45-55 degrees N. It grows on rotting branches of certain trees on humid winter nights when temperature drops below 0 degrees Celsius.
It took 100 years to confirm Wegener's hypothesis that a fungi was involved with the production of these delicate strands with a diameter of ~ 0.01 mm (0.0004 inches).
When the melted ice was analysed, the byproducts of the fungus Exidiopsis effusa was found in every case of hair ice growth in a mechanism called ice segregation.
It is hypothesised that the ice hairs are stabilized by a recrystallization inhibitor provided by the fungus. The action of the fungus enables the ice to form these hairs and to keep this shape over many hours at temperatures close to zero degrees.
