I am putting my nearly 20 years experience of mushroom picking in your help. I will revel to you mushroom`s Latin and common English name.
All you need to do is to take two pictures of the mushroom (one from above, and one from below), and to tell me where you found it (country, environment, season).
Note, some fungi are impossible to determine without consulting microscopy or its smell, taste, and place where it grows.
If it is not possible to determine exactly species, I will at least determine the group (genera) where it belongs.
I will identify one mushroom for you.
