Mushrooms on plum tree
My mum has an old plum tree in her garden, probably 20 years or more old. It has always produced loads of fruit until a so-called tree surgeon hacked it back early this year. It's been pretty grim looking since then. Today she noticed the trunk and branches are covered in mushrooms. ( Pic is below. ) It has been several days since she was near the tree so she's not sure how long they have been there.
I've been googling but the only similar thing I found was mushrooms growing round the base of the trunk, not all over. Will this tree have to be cut down ? Or is there something to treat it with ? Mums also worried it will spread to her other fruit trees. I would greatly appreciate some help on this ! |

Also, stone fruits are generally not long-lived. However, I would strongly urge you to have a different tree expert examine the tree. -- David E.

The mycelium then moves up the crown roots to the trunk to develop the ribbon-like structures called "rhizomorphs." From the rhizomorphs finally come the characteristic semicircular "conks" or fan-shaped brackets at or near the base of the tree. These are the fruiting bodies, which release millions of spores over the next five to six months."

Dammit I used to know what victimizes the Prunus trees, but for the life of me.... OK nevermind. |

Quote:
I would say it is unlikely to be a threat to other healthy trees in your garden: it is extremely common, you'll find it everywhere in your local woods, so the spores of this fungus are everywhere all the time, so having a local source of spores is unlikely to change the risk level much. Personally I'd plant another tree now as it is bare-root fruit-tree planting season, just in case the other can't be saved. You mustn't plant a replacement in precisely the same location anyway, so you'll have to find a new location for the replacement whatever happens. |
