These appeared on ground under maple and yellow birch trees, they are about 1 1/2" in diameter and the insides look like jelly what are they called? Thanks

I don't know a thing about Fungi but they look like some of the common mushrooms I see when the ground is very moist after we get a lot of rain. Some mushrooms are highly toxic so if you have plans of harvesting them, I'd wait until you have an exact ID. Here are two pages with info and photos of the ones they remind me of:

Agaricus bisporus:

Agaricus campestris:

Hopefully someone will be along soon to give an exact ID.

I am curious as to what your interest in a specific ID is.

Might be a witch's egg.

Clathrus archeri - another creepy one; aka Devil's Fingers.

I am only guessing.

There is a Fungi forum here on NGA. You might visit that forum and read the threads.
