Had a tree die off on me.
I believe the tree is a Black Oak (part of the red oak family of oaks).
I noticed that it was shedding it's bark a couple of months ago.
About 10 years or so ago I had several oak trees succumb to this particular disease but other than "some kind of tree virus" I never really got a real cause and kind of moved on.
I did a little internet searching and came up with Hypoxilon canker.

Kind of hated to see it die off. I didn't notice any issues with it last Summer and Fall. Wasn't very big, the butt at ground level was just about 24" around and tapered pretty quit to about 14" at the 12' above ground level.
I'm going to get after it with my Alaskan Chainsaw Mill and make a few boards out of it should be able to get a a couple of 1X8s and one or two 1X6s out of it. as well as a few hunks for the wood lathe.

I'm thinking oak wilt since it spreads via the root graphs in red and white oaks. That makes sense since you have had several oaks die. Seems to affect red oaks faster than white oaks.

I was thinking that too. I didn't know about the difference between red and whites, but it makes sense since white oak is closed grain and red oak is open grain. (perhaps the fungus doesn't care about that and it doesn't matter if I think it makes sense) Is it treatable with systemic fungicides?

No, unfortunately.

"Hypoxilon canker."
Related to G-23 Paxilon Hydrochlorate?

That's just all we need. Trees becoming Reavers.

Effective control of oak wilt focuses on hygiene and sanitation. Systemic fungicides are used to control spread to susceptible trees around the periphery of a hotspot. The diagnostics, fungicide and application equipment is expensive enough to consider hiring it out, but probably within the realm of most of us.
The key thing is read the label, understand the label, use PPE, grok molar calcs when mixing, and sourcing the product. Its been a while since my CPA* license lapsed, well before Oak Wilt took root, but sale of fungicide in the concentrations needed for effective injection MAY be limited to licensed applicators.
Give Mr. Haney a call, down at the extension office. He'll know.

All you ever wanted to know about oak wilt

I do disagree with their chemical control section, mostly because it is a crap shoot, expensive, and it is hard to treat every compartment* of the tree. Basically, you're just kicking the can down the road.
*interior of a tree isn't uniform, you need to hit every vascular tissue "tube" to even get possibly get 100% control.

Don't you mean Mr. Kimble? =D

Yes, that's corrupt. Wait, uh no, that's wrong. I mean that's correct. Ummm. No.not correct that i meant Haney, You're correct that I meant Kimball. Hank Kimball. County extension agent.
Hold on.. I'd better check.
Yeah. Me.

Oh darn, I misread that as Abortionist. =|

Never really looked up any diseases. 2022 saw a pretty good drought most of the year at my parents land. Just enough rain to keep thing green, but not enough to really allow anything to grow. Probably 1 in 10 post oak trees died, or it seems that way.
-
We had a dry-ish Summer but not really seriously drought level. But could have been enough to push a less than robust tree over the edge.
I got a confirmation of Hypoxilon canker by multiple people from a forestry forum I spend a little time on so I'm leaning that way.
Weather permitting I'll break out the Alaskan chainsaw mill next week and try o make some lumber out of the log. I'll post up some pics when I get it doen.

Ent reavers. They get hasty.
