Tiny white tendrils of ice grow from a stick lying on the ground with brown leaves and one green plant. The ice looks like feathers.

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 #Nature #Photography #Nikon

A dead branch against a background of dead leaves. The branch has white ice formed along it that looks like hair or candy floss.

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.

Maanrajassa makaavan lahon oksan sisältä pursuavaa hiuksenhienoa jäämuodostelmaa, ympärillä näkyy sammalta, ruskistuneita lehtiä ja oksia.

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

Rare 'frost beard' ice formation discovered by a hiker Capillary ice, a rare winter phenomenon formed by Exidiopsis effusa fungi, amazed a hiker during a walk in freezing January.

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.

Mushroom Monday. Sort of. A little frosty morning hair ice. She’s so glamorous. #nature #outdoors #pnw #ExidiopsisEffusa #HairIce

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
