Pholiota squarossa

[Lazarus2]

Anyone know how this fungus affects Ash (Fraxinus excelsior)? Found lots of it on an annual inspection. 10" diameter clusters growing in-between the buttresses on all sides.

Nothing known about it on Ash in UK. First time I've seen it.

Apparantly notorious on Poplar in North America.

Anyone with experience of it?

My reasoning is, if its there, it could be secondary to other more aggressive fungi?

Hey Laz2, do you know if this funghi occurs on conifers?

I think I saw what looked like it on a spruce today?

Clusters - the tree looked good!

Don't know.

I probed the Ash that I found it on (just finished writing up the report actually). Good drilling resistance and just a small pocket of decay, but not where the fungus is situated. Full healthy crown too, but some root damage.

I expect it is feeding off the dead roots. At least I hope it is, because I recommended it stay and there is a house in falling distance.

Laz, this funghi will infect spruce(Butin 1996)and other conifers.

Some other good info in there,

'If the stability of an infected tree becomes uncertain, generally P. squarrosa is not the only fungus involved'.
