Here these are found at elevations of +10,000 feet (+ 3 km).

First of all, thank you for converting the feet into km for me! I noticed that you did it in some other comments you left me and it is so so kind and thoughtful!

Second, 3 km high! I didn't realize that you live at such high ground!

About the mushrooms... this penny bun doesn't have a poisonous double here and it is easy to be distinguished. And they are truly delicious! And your wife is lucky to have a royal food taster at home :D

We call them манатарка (manatarka). They are expensive and valuable mushrooms here and around Europe as a whole.

The other one that is in this post could also be found in the US (links here and here). Although there is another mushroom that it could be mistaken for (but not a deadly one).

I am very happy that I can share my mushroom passion with someone. It's a relatively new thing for me and most of the times I am only observing and taking pictures :)
