Basal Holly fungus ID please

[Big Beech]

Hi Guys,

 

ive had a look thru my book, but unable to ID this.

its like small bubbles, of black crispy puffs. only around the base of the tree, but not all the way around.

the tree is approx 18" diameter and approx. 35ft high.

 

thanks,

Kretzschmaria duesta. Not seen it on holly before. Is it coming out?

[Alinicoll]

Looks like Kretschmaria deuata. You need to investigate the root conition, it is often very severe.

[Big Beech]

do you mean is the tree coming out? the client wished to retain it.

+1 for duesta A tricky one to assess, hard to see in pics but the road doesn't look busy, any other targets to take into account?

formally known as ustulina? - 95% on limes - not seen it on holly before

[sloth]

yes formally Ustulina deusta. Most often on lime and beech, then sycamore in my experience. Never seen it on holly but it is known to have a wide host range...

thats interesting. there atr two of the largest sycamores i have seen, just out of shot from this holly on the right. i will also check these shortly.

 

what is the recommended proceedure for this fungus? the tree at this stage shows no ill health in the crown and has a full and dense crown at that...

 

Perhaps reduce to avoid with throw?

on Holly who knows? - do some tests at the base of the trunk to assess decay im sure alot of peeps would be interested

From the photos, I would asume that the buttress the Kretzschmaria is fruiting on is dysfunctional and extensively decayed. Often canopies don't show much if any symptoms.

 

This tree has little future imo.

 

This is what is likely to happen (here on beech).......
