Black fungus on lime

[Liam Bellamy]

Can anyone help me identify the fungus on this lime tree? It’s on a mature lime, it’s been heavily reduced in the previous 5 years..

Any help appreciated,

Thanks

Not likely to be fungi, possibly bleeding canker like Phytophthora (P. cactorum or P. plurivora)

Or possible vascular dysfunction caused by a root pathogen like Armillaria.

I was thinking bleeding canker but now that David has suggested it I'm all over it ! 😁

Id go with David’s doagnosis(he’s usually right). You can get some easy to use testing kits here https://www.pocketdiagnostic.com/onlineshop/pocketdiagnostic/phytophthora-single-2/

£10 a test. All my clients so far have been too mean to pay for me to confirm Phytopthora with these, but I will try one soon even if I have to pay for it myself. What?

Wonder if you could detect Phytophthera on any given wood sample[emoji848] Or would you have to be very specific in where you get your samples from the right (infected) section of the trunk. I’m thinking cankerous stems sections as opposed to whole trunk death from Canker.
