[Fungus]

Pholiota genus ... possibly P. squarrosa.

 

Arran & David,

Definitely panic fruiting biotrophic parasitic P. squarrosa.

Hes right, i got an email form one of the hort teachers ar writtle, (i'm in arrans class)

 

Subject: Pholiota squarrosa on Styphnolobium japonicum AGM (Pagoda tree)

 

 

 

Dear all,

 

 

 

I have taken this from the following source - http://www.deeplyrooted.co.uk/resources/PD-assignment.pdf

 

 

 

This fungus has the ability to compromise the structural integrity of an

 

infected tree, and although it is not a widespread disease at this time in

 

the United Kingdom, it does indicate a pre-existing infection which will

 

require a closer inspection of the tree. The potential damage caused by

 

a structural failure requires serious management considerations to be

 

undertaken for the retention of infected trees.

 

 

 

Control:

 

No known control measures to prevent spread of

 

infection.

 

 

 

Chemical:

 

There are no known chemical controls for this

 

fungus.

 

 

 

Biological:

 

There are no known biological controls known for

 

this fungus.

 

 

 

Cultural:

 

Good arboriculture practices such as the removal of

 

broken/damaged stubs will limit entry points. Good

 

growing conditions to limit root compaction,

 

pollution, stress, dehydration and nutrient deficiency

 

to provide optimum conditions for root development.

 

 

 

Management:

 

Fungus appears to affect structural integrity of the

 

tree. Where necessary fell the tree, and remove all

 

infected wood from the site. Remove stump to limit

 

food source for remaining fungi to live on (fungi is

 

saprotrophic)

 

 

 

 

 

I thought the best option for the time being would be to stop traffic flow through and around the tree to minimise compaction. Charlotte is talking with Darren Blunt for further advice and guidance.

 

 

 

Has anyone any thoughts, confirmation on problem – John?

 

 

 

In the meantime if you could pass this on to your students – Interpretation going out this morning.

Pholiota squarrosa is not saprotrophic, it's a biotrophic parasite decomposing dead wood (cellulose) to panic fruit before the tree is killed and dies.

I'm not gonna argue, i really don't know

I have yet to see a tree fail soley due to P. squarrosa.

I have yet to see a tree fail soley due to P. squarrosa.

 

I've seen some Salix, Populus, Robinia and Platanus fail soley due to P. squarrosa.
