Rare Hair Ice: Caused by a Fungus!

A rare incidence of ‘hair ice‘ has been recorded in the Scottish Highlands this week. Usually found around decaying wood, under specific weather conditions ice forms along the thin threads of a fungus Exidiopsis effusa. It only forms when the humidity is high and the air temperature is below freezing but the mechanism of its production remains a mystery.
