These are hyphae of a still unknown fungus, forming a white large net-like mycelium. The total space occupied by these white to whitish threads was about 1/4 of square meter, and they were covering the upper surface of a tree stump, as well as a piece of wood discarded next to it.


Seen during my last weekend trek through mixed forest (oak, beech, spruce and fir) on a rolling hills at the feet of Jura range; Geneva lake valley.


Thanks Mark for help with the ID of these.

Thanks Mark for help in narrowing down as much as possible this one, much appreciated our discussion on facebook.

Thanks for posting this Zlatan. I have a very similar one where the "web" goes from a small tree trunk onto a large leaf that is touching (and now attached to) it. I will be keeping an eye on possible IDs.

Beautiful series Zlatan. Natural art. Sometimes in wet forests if we peel a big sheet of bark from a fallen log we see similar. Here the larger and more prolific ones are often Stereum. I see your log is possibly pine which might be a clue to an ID. Fungal hyphae.
