Mushrooms, edible or poisonous?

Grandma found these in the backyard, Washington state. 

We are trying to research what type they are.

Good people on Facebook reported it as:

• Looks like Amanita Pantherinoides buttons... toxic, not for consumption.

The problem with mushrooms in general, 

And specifically with this one is that they look a little like:

• Shiitake, 
• a little like puffball,  
• white flower mushroom.
