From today’s chilly hike: #hairice! #exidiopsiseffusa was described a little over 15 years ago as the organism behind this beautiful phenomenon. Hair ice is found in a limited range (45-55 degrees N) around 0 degrees C in humid conditions. #kawkawalake #hopebc

Hair ice in a Midlothian woodland yesterday morning. A rare and ephemeral phenomenon, formed on dead wood in the presence of the fungus Exidiopsis effusa. Forms when ambient moisture and temperature conditions are just right. #Fungi #ExidiopsisEffusa #Nature #Photography #Nikon

Another first for me aka another dog walk bonus. Hair Ice in the local woods today. Apparently a fungus, Exidiopsis Effusa causes it on rotting broadleaved wood in certain conditions.

Tänään oli taas otollinen ilma, eilisen plussakelin jälkeen pikkupakkanen. Tuomesta katkenneissa oksissa sai ihastella #liilatali 'n aiheuttamaa #hiusjäätä.

Winter is here! Hair Ice in a Midlothian woodland this morning. Formed on dead wood, mainly beech. Even found a group of Rosy Bonnets (Mycena rosea) looking after a little bit of it. #ExidiopsisEffusa #Fungi #Nature #Photography #Nikon

Rare ‘frost beard’ ice formation discovered by a hiker: The winter chill in early January surprised many across England this year. On January 11, 2025, a casual walk through the Devil’s Punch Bowl turned into a moment of astonishment.

Yes. Just posted a 📸 taken on Saturday in Yacolt Burn State Forest. Very cool!!! It's actually caused by the #fungus #ExidiopsisEffusa on dead, barkless branches of broadleaf 🌳.

Check out this #HairIce aka #FrostBeard or #IceWool
Formed by the #fungus #ExidiopsisEffusa on dead, barkless branches of broadleaf 🌳. Forms when temp is slightly below 🥶, air is humid & fungus is present on the wood.
Fungus releases 💧 from the wood >> freezes into very fragile hair-like strands
