Peppery milk-cap

I will check today. :-)

Andres, this is not an Agaricus because if you look at the soil that the mushroom grows on you'll see it's a forest floor. The only species of Agaricus that I know grow in a forest are A. Silvicola and A. Silvaticus (and these look different). Plus A. Arvensis has another type of gills and another color.
And I bet that if you tear the mushroom in the picture, a white milky sap will be visible.

WELL DONE¡¡¡¡
SPECTACULAR SPOTTING¡¡¡
