Wild Wednesday, Puff Ball Mushrooms

We went for a walk in the woods this weekend and came across these adorable little mushrooms. I think they are puff balls, as they are a white rounded mushroom growing low to the ground with a short stem.

They have small spikes or warts on them as once sight referred to these as pineapple markings. I guess there are some poisonous look a-likes to this mushroom, and some can be deadly.
