What is this growth on fallen tree branches? (lemmy.world)

I went for a walk in the woods and found multiple fallen branches with this fairly long growth on them.

I assume that it is a fungus of some sort but does anyone have more info on what kind it is?

I found so many that I eventually stopped taking pictures of it. But I haven't seen this before so I was surprised, as I spend quite a lot of time in the woods.

https://en.wikipedia.org/wiki/Hair_ice

Hair ice, also known as ice wool or frost beard, is a type of ice that forms on dead wood and takes the shape of fine, silky hair

That is really surprising because it didn't feel that cold. It's actually +1C at the moment so did not even consider ice!

It says in the article it can persist for days.

Yes! I am not doubting it at all. I am just surprised at it being ice (even after reading the Wikipedia link)

[–] [email protected] 24 points 8 months ago (1 children)

Though apparently only forms because of a fungus!

You should submit some of your photos to Wikipedia. They're very clear compared to some of the handful in the article
