This is hair ice. It is formed on dead barkless wood and a fungus called Exidiopsis effusa is the main reason. I found this and many more, during late autumn in a forest in Northern Denmark

    You’re welcome!

    As far as I know, and I can easily be wrong about this, it mostly forms in snow free weather and when the temperature is just below freezing
