chestnut tree bacteria ID

[Mitchell]

I have included pictures of the leader I removed from a chestnut tree with a shear plane fracture and the orange ooze coming from it. The owners opted to have it removed as cabling it is was more expensive then removal. I looked around for information on what the pathogen might have been but never found a decent answer; any thoughts would be appreciated.

Sorry I can't help with the ooze ID. I'm no expert, but are you sure that is a chestnut? Seems large for an American chestnut and the bark is too smooth for a Chinese Chestnut. Kinda looks like a magnolia from the bark.

sorry folks

horse chest nut; [aesculus] family not [castanea]

Not sure what the ooze is but it looks like the tree was wind-sheared/stress fractured making an entry point for some sort of pathenogen (flux-type? dunno), my first thought was that it weeping sap from the fracture. Curious to see what others say, we have alot of these trees in our area and it'd be nice to know if there is something they are prone to and to watch out for. A question I have is, is this something that will affect the other part of the tree, ie., will it move down and into its base and thereby compromise it as well?

Aha - wasn't thinking horsechestnut. Usually call those Buckeyes around here. The bark does look like a Painted Buckeye - aesculus sylvatica. I also thought it was sap ooze but I haven't seen that on any buckeye around here.

the ooze

the ooze was rusty orange, Never say never but it seems very unlikely it was sap. The rot did seem to travel down into the stump. The crack was 5 feet up stem.

the closest I can narrow it down to was listed at these links...
