Ice Hair fungus (Aberfoyel)


On humid winter nights, you may be able to find these peculiar ice crystals that form on Rotting Wood..
Looking a little like fur, or candyfloss, these hair-like whisps appear overnight and then melt when the sun comes up..
Hair ice is caused by a fungus called Exidiopsis effusa, and the action of this fungus is to enable the ice to form thin hairs – with a diameter of about 0.01mm – and to keep this shape over many hours at temperatures close to 0°C,
