The acorn?

That is really odd. I've grown many acorns and have never seen anything like that before. Do you know what species of Oak it is?

Here is one of my seedlings
Here is one of my seedlings, now 3 or 4 years old. It kept this swelling and now has a lovely taper to the trunk at a whopping 3 inches tall. I have no idea what kind it is, I just pulled it out of the ground like a weed and planted it (and several others).

Can you check if the "shell" still have the seed in it or if it is empty?
I am thinking he bulb is the seed itself that was ejected from the shell coating and that you have 2 trunks-one is out as you see, the other is still wearing the coating like a helpmet (just a guess).

Interesting. I just did a little research and learned a new word while I was at it. Evidently, oaks usually have a hypogeous emergence pattern, which means that the cotyledons produce roots and leaf stems that emerge from the cotyledons and grow in their respective directions. This means that as they grow, we should see a stem and root both emerging from the cotyledons. Since the common emergence point for the leaf stem and roots in your picture is that bulb that you have there, I would suspect that that is the cotyledons, and if you open up the seed shell, you'll find that it's empty, as the cotyledons have been pushed out. That's just my guess.
Reference page: Seedling Emergence Patterns
edit: basically what Dario said, except it's just one "trunk" (the other is a root).

That is really interesting!
Generally, the cotyledons remain in the shell and feed the radicle which differentiates into roots and the shoot. It looks like the 'bulb' is some sort of carbohydrate storage structure.
If you gently peel the shell away, you should find the partially spent cotyledons.

I suppose, when the image is viewed at its large size, those seed coatings aren't showing enough crack for the cotyledons to have accidentally slipped out. That bulge does sort of look like a potato, doesn't it?

I wonder if it's intracellular mycorrhizal fungus (similar to ectomycorrhizal fungus discussed in this article) ...
... maybe it's truffles!

I think it is live oak acorn!
It is what I'm thinking!
The shell was removed. The cotyledons remains in the shell!

I believe mine is live oak as well. Like I said mine has kept the swelling and it is now barking up pretty nicely. It also has radial roots coming out from it. Odd but cool.

It is great when you learn something new.
I have a small Live Oak (my only one for now) with similar base bulge as posted by Clyde. True, it is odd but cool LOL. It is about 2" dia though the main trunk above it is less than 1/2" IIRC. The bulbous base has nice crackly bark already.
I am trying to improve the transition area (right now it is almost like a graft) to be better by having more branches there and induce swelling.I'll try to snap a pic later and post.
Thanks!

I'm kinda sad you chopped it up.
I would have just looked in or split the shell casing to investigate but let the growth so it can still be planted. I guess you have several so it is okay.The bright side is that you shared and several people learned from it.

As promised. A pic of my live oak w/ a bulged base taken last month. It has multiple buds now.

As purchased, before the chop. I am re-hydrating it here since it tumbled all around my in-laws truck bed and lost most of its soil during a 6 hr trip to Austin (w/o me). Obviously it survived but I was shocked when I first saw it. I could have lost a $8.00 tree!

I can see yours have lot of potential!
Don't worry Poink88 because it's not mine! ;-) . It belongs to one of my friend. I collected about 1000 acorns this January, then sent them to my friends who are living in Vietnam. We form a relative large bonsai group in VN and I have sent quite a bit of JBP seeds, oak seeds, olive, pomegranate since those trees are quite new in tropical areas. So far, they have been doing great there.I'm kinda sad you chopped it up.

ha, you're lucky!.As promised. A pic of my live oak w/ a bulged base taken last month. It has multiple buds now.

I transplanted my cork oak seedling last year and didn't see this phenomenon!
Your tree has interesting bulbous tap root!
