Glanced over at my neighbors yard today and saw these weird lookin' mushroom formations. I don't remember seeing them there yesterday when I got home from work, tho.

It is late October and the temp got down in the high forties last night. Can mushrooms grow that fast in those kind of conditions?

*Edit*

I Googled "can mushrooms grow overnight" and got this answer.

"Plants and animals grow through cell division. They have to produce more cells , to get bigger in size. Cell division is relatively slow process and requires a lot of energy. The mushroom body also grows by cell division. However, the mushroom fruit does not grow by cell division. Just about as soon as it starts to develop, a mushroom has almost the same number of cells that the mature mushroom will have. The mushroom increases in size through cell ENLARGEMENT! This means that the cells can balloon up very rapidly. Very little energy is required, basically the cells just enlarge with water. So a mushroom can increase in size as fast as water can be pumped into its cells. Almost overnight a mushroom can go from a pin head to a large mushroom."

So I guess they do grow overnight!

I love the Interwebz!!!
