Each strand is astonishingly thin, around 0.01 mm in diameter, and can extend several inches long, giving the appearance of soft, fragile hair on tree bark. The formation of hair ice requires very specific conditions: temperatures just below freezing (between -1 and -5°C), high humidity, and a supply of moist, decaying wood. The fungus releases gases that prevent the ice from recrystallizing, helping it to form fine, silky strands instead of compact frost. Once the temperature rises, the ice filaments disappear as mysteriously as they formed.
Though sightings are relatively rare, hair ice has fascinated scientists and nature enthusiasts alike for centuries, often appearing in temperate forests during early winter mornings. While it looks magical and delicate, hair ice is fleeting and melts quickly when touched or exposed to direct sunlight. Understanding this fragile frost phenomenon sheds light on the hidden wonders of the fungal world and the remarkable conditions that produce such intricate winter beauty.
