I just heard back from the company that makes the Great White Product, and here was their response:

Many thanks Dave, for the reply and information. I appreciated it! I've emailed the company that makes the Great White product, in hopes that they can shed some light on this. Doing some reading on the Psathyrella mushrooms (http://www.mushroomexpert.com/psathyrella_candolleana.html), it sure does seem like that is what I've got growing.

Hi all, I planted some vines in my backyard about 3-4 weeks ago, and have watered them twice (initially, and just yesterday) with a mycorrhizal product called Great White (http://www.plant-success.com/index.php/mycorrhizal-products/great-white-mycorrhizae.html), to help encourage/establish root growth. There used to be a small peach tree near where this vine is now planted. The tree was cut down about 4 or 5 years ago and the trunk (about 3&1/2" dia.) and some roots remain. I've noticed an explosion of mushrooms near that turned up dirt where one of the peach tree roots is, both times I applied the product. I realize that the mycorrhizal I applied to the soil would encourage fungal growth. I just didn't think about the possibility of it encouraging fungal growth on the surface in the form of mushrooms. My questions are: What kind of mushrooms are those? Should I be concerned with those mushrooms near the new grape vines? If so, how should I remove/control their growth? Could that Great White product be the source of the mushrooms? Or, is it simply feeding the spores/mushrooms already present on the old peach tree roots? Thanks! Note: The first three pics are the most recent, taken this morning. First pic is a closeup of the previous round of mushrooms, they are found in the 2nd pic (near bottom) showing both old and new. The bottom two pics are the original mushroom growth noticed about 7-10 days ago after the 1st application of the mycorrhizal product.
