This is the first time I have seen this mushroom and I don't have the slightest idea what it could be. Any help would be appreciated. The habitat is a forest where there are pine trees. It grew on the ground (not on a decayed piece of wood). No particular odor. The stem grows wider downward. The cap is small (3 - 4 cm)The cap is pale pinkish brown, protruding in the centre. No spore print. (Sorry!)
