can someone please help me identify this mushroom!

I found two mushrooms in my yard today and they both look the same. Ive never taken shrooms before and wanted to know if these were in fact psycolibin mushrooms..

Could you magic up some pics so we could tell you?

sorry. ive been trying to but when i try to attach them a little red circle with an exclamation point pops up! but they have a white stem, white cap with a little brown on the middle of the cap where it looks like a nipple. and its brown underneath the cap. about 4 inches tall and the cap is about 1 to 1 1/2 inches wide.

Oh and its in north central FL.

Have a look here:
