We may cut the stem of a mushroom, say of the agaricus campestris, close to the cap, and place the latter, gills downward, on a piece of white paper.

This peculiarity has been observed also in the case of another species of agaricus.

The plants should thus not be confused with any of the species of agaricus to which the common mushroom belongs, since in those species the gills become dark brown or blackish when mature.
