U deusta?

[Dean O]

I feel these are Ustilina/Kretz (which is it now?)

Crown is perfectly healthy, and weighted towards a property, some 'mechanical' damage around base,

The fungi, top left of picture 4 in the wound looks like it has a bit more substance to it - something desiccated - does anything in particular hang around with Ustilina?

 

thanks

Looks like it

Yep - time to remove the tree!

Hmmm, more often than not bad news, and a healthy crown isn't uncommon with it. On a sycamore leaning toward a property? Be a brave man who leaves it vertical...

Pretty classic Kretzschmaria deusta. I know, that name still seems unfamiliar. I learned it first as Hypoxylon deustum, then Ustulina deusta. But in following the rules of the nomenclatural code, it does indeed fall into Kretzschmaria, which was published as a valid genus in 1849, although deusta wasn't recognized as that being in that genus until 1970. Oh well, more than you wanted to know!

I'd got a feeling it had gone back to ustilina for some reason.

Thanks for the info tho.
