Hair Ice
Hair ice forms on moist, rotting wood from broadleaf trees when temperatures are slightly under 0 °C (32 °F) and the air is humid. Generally when a cold period follows a rainy weather period.
Each of the smooth, silky hairs has a diameter of about 0.02 mm (0.0008 in) and a length of up to 20 cm (8 in).
The fungus Exidiopsis effusa has been proven to shape the ice into fine hairs by providing a recrystallization inhibitor similar to antifreeze proteins.
