Phellinus tuberculosus

[Fungus]

Documentation of the biotrophic parasitic Phellinus tuberculosus (= P. pomaceus) slowly killing six about 40 years old plum trees standing in a row.

Together with the development of perennial brackets, the mycelium causes the formation of egg to fist size cankers (tubercules, tumors) on the major branches of the crown. After 10 to 15 years the crowns have lost most of their branches.

Photo 4. Cankers (tubercules, tumors)

very very common here in the U.K and is often in co decays with Laetiporus, a combination see repeatedly in the street planted prunus pissardii's

In The Netherlands, where it is very common too, it is also associated with silver leaf disease caused by Chondrostereum purpureum. In garden centers, Prunus serrulata sometimes is sold with Astkriecher of P. tuberculosus in the "armpits" or at the downside of branches.

what do you mean by asthriecher in the arm pits gerrit? is that something we can see in nursery stock and learn to avoid?

sorry i get it now!

every decent sized cerasifera i ever see seems to have it! very useful documentation of decline thanks Gerrit - update on the radiata - the owner is happy with the insurance situation on the tree having had it inspected so remains to be seen if she will let me do some pruning.......but its staying put anyway. Thanks.

Love the way that the owners of this property obviously have an affinity for the remains of this tree & its fungal inhabitants

David,

Nice documentation . Do you know whether the brackets close to the cut were there before or appeared after the tree was felled ? Both ways, it seems like an example of panic fruiting with as much fb's as possible.
