A fly, I think...
The two "exhaust pipes" on the rear remind me of a Syrphid.

However, I could be way off base, so please wait for the opinion of an expert.

You might be off base, but yo
You might be off base, but you had good arguments. The typical feature of Syrphid larvae is that the two posterior spiracles are close together, but there are more families that have LONG "tailpipes", and to have the very white larvae which are round and pointed, are typical for Drosophilidae! Although 6 mm is a bit long and it would help to the the anterior spiracles, but if I have to place my money somewhere, I would say drosophilidae...

Tail pipes
Yes, the "tail pipes", spiracles, make me think of Syrphidae. I am a little more familiar with the ones that feed on aphids; I don't know about other syrphid larvae, though.
Aparently some live under bark. See: this one.

I'm thinking fly also..
Found this which looks very similar except for the "exhaust pipes".
Also, what I'm thinking might be sap exuding from the stump might be a slime mold or a fungus, as it's always wet under that piece of wood. It's been very rainy here this fall.
