Beautiful! These look like Kuehneromyces mutabilis to me (but beware deadly poisonous lookalikes!)
This looks very similar (from the latin name wikipedia page).
Yes, they are very recognizable and the mushrooms in your photo are almost certainly K. mutabilis.
However, Galerina marginata can look very similar under certain circumstances, which is why harvesting and consuming K. mutabilis is best left to experts. These species have been known to grow on the same substrate right next to each other which is why you should ID each mushroom individually.
Personally, I think can tell the difference quite confidently and I still don’t harvest K. mutabilis. (I’m still waiting to find G. marginata a few more times and get to know them better.)
I’m very far away from trusting myself to harvest edible mushrooms, but thanks for the warning anyhow.
I just love how they grow up the tree.
