What a coincidence! During the hard freeze on New Year's Eve here in Austin, TX, I discovered a field of this stuff in my back yard. When I first saw it, I didn't even recognize it as ice! It looked more like a fungus at first, and only after touching it and seeing that it was dissolving did I realize what it was. After some Googling, I came across this exact Wikipedia article (thanks Wikipedia!).

You weren't too far off:
> In 2015, the fungus Exidiopsis effusa was identified as key to the formation of hair ice.
