Calocybe gambosa. Maybe?

Is anyone out there familiar with Calocybe gambosa. The mushrooms I found have the right morphology, spore print and habitat for St. Georges mushroom. It is a locally common early spring mushroom in Europe but has also been reported in North America and it is not uncommon for some early mushrooms to fruit in late fall. I eliminated all the listed lookalikes I could find. Pictures on the net varied somewhat - the ones from France were spot on. If they pop up in the same spot first thing next spring that should nail them down.
