Dead oak

[davidwyby]

In SoCal….live oak. No bug holes. Just red sap I think.

We’ve had drought and lots of them die from bugs.

Sap suckers do their damnedest as well sometimes.

Appears to have been “sweating”. Still had brown leaves, solid wood with moisture.

Strange looking. That's really sap?

Fungus

That's what I thought it looked like.

I have no idea. Feels like half dried sap but not very sticky.

I'd go more toward a defensive weapon produced locally by the wounded tissues to close the opening and bury an eventual boring larva. The cherry produces a gum which can look like an extruded form like that if there's a well defined opening, but more a globular if it's a deep and contaminated wound. It can be seen on the apricot trees too where some insects bore the twigs.

Jelly fungi. Exidia glandulosa
In cherries the gummy globs are called weeping guminosis.

Gummosis. 😀
