Hi everybody.
I saw this lichen, what could it be? Thanks

Others lichens I can't identify.

A very common lichen in Italy: Xanthoria parietina. Nice apothecia.

A question about mushrooms. Why can't we froze raw mushrooms? Which is the risk? Thanks

A nice Parmelia sulcata on Larix.
Please note network of elongated pseudocyphellae.

Hi everybody, yesterday, during a walk in mountains, I saw these patches on
bark. I could not see apothecia/soralia.
Any ideas?

Yesterday, while walking with my dog, I saw this beautiful lichen with long cilia on Acer platanoides bark. It is Physcia ascendens and I want to share it with you.

Hi everybody, I'm new here. I live in Italy and I'm here for lichens. On an island, close to Venice, I saw These lichens.
Can you identify anyone? Thanks
