They are probably both wood mushroom agaricus silvacola. The ring on the stem isn't very big and the bottom one has a yellow staining to the cap. However unless you are confedant you can tell the differance in smell of the poisonous yellow stainer [iodine] and a wood mushroom[aniseed] don't take my word for it.
It could also be agaricus essetti [type of wood mushromm more common with pines]
