#4 and the last one, probably, are Paxillus involutus, (in Russian Свинушка тонкая), an unedible mushroom that can extract and accumulate toxic stuff from the soil, and restroy the auto-immune reactions of your body, they look meaty and delicios, and always mature in such a nice splendid harvest-looking families..... but better keep away from them! :P

a nice walk you had. cheers!
