Massaria on the March

[breffni]

What do the fruiting bodies look like? Is it originally from the Netherlands/ Germany area?

Massaria (although a fungi) doesn't produce a fruit body.

 

It's sporalates directly on to the bark surface.

 

 

It's been found from the med through to Northern Europe.

just a small question does this fungus/disease affect the oriental plane trees

 

I've read that it can affect The London plane - Platanus x acerifolia, Oriental plane, P. orientalis - and the Western plane, P. occidentalis

David...once the tree has dropped said limb or it has been removed what then are the implications, will the massaria carry on to the parent limb or is the tree now free of it ?

[David Humphries]

Expect other limbs in the same tree to become infected (if not already) and start to shut down.

 

 

If a tree is stressed enough for the latent spores to infect one branch in the first place then I imagine other subordinate branches will be at risk.

Could this then lead to the whole tree shutting down ?

[David Humphries]

We are (increasingly) seeing, whole trees shutting down that have Massaria affected branches, but I wouldn't say that the Massaria is the primary reason for complete shutdown of the whole tree system.

So does this work in the same way as Dutch Elm Disease where the tree slowly but surely commits suicide? will trees recover or is it too soon to say?

Massaria is a fungal disease of branches where as DED is a vascular disease of the entire tree system.

 

The London Borough of Islington, The Royal Parks & Treework Environmental Practice are leading the way with trials regarding irrigation and soil porosity to see what can be done to improve the growing conditions for urban Plane trees.

 

This study will no doubt take some time to provide data and best practice guidance.
