Is it Kretzschmaria or something inocuous?

A few feet off the ground on a sycamore and growing along some splitting bark on a horse chesnut.

It looks like Kretz but I have never seen it so High up the trunk. One pic shows it on a closed wound so I would guess it could be  bitumen painted on the wound and on the crack.

I agree that bitumen seems likely. Kretzch does get canny high up trunks when there's wounds in them though.

Here's one of Kretch getting quite high up.

Here's another wi k very high up. First was lime this is a beech. Raised spit of land. Chalk with extremely thin soil horizon. Stem has K up to 1.5m above buttresses. Mind boggling how this was still vertical.
