The Ganoderma thread!

[Fungus]

last week I found this recently fractured Quercus rubra (during the storm which took 5 lives on the Pukkelpop festival in Belgium). On the stem base there were fruiting bodies of Ganoderma applanatum, but the fracture was 4m higher. On the broken stem I found one small FB, more spherical. Would this also be G. applanatum or maybe another Gano? I did not having a knife, so couldn't take a sample to check the 'flesh'. The fracture looks like there was a hollow (maybe a woodpecker hole).

 

Tom,

At that height, it probably was a panic fruiting bracket of G. lipsiense coming from the mycelium growing upwards while causing an extensive white rot with delignification, for which the woodpecker's hole would have been a not to be ignored warning sign, in the poor quality wood of the central column of the tree.

Spotted on roadside oak about 3 or 4 years ago. This is it now, crown appears healthy, despite being hemmed in with concrete

Without microscopical identification, I'm 95 % sure this is G. australe.

May I ask how you come to that conclusion? And in your opinion, should I let the relevant authority know about it, so they may investigate further? Thank you

Two examples of G. lipsiense fruiting from dead wood (probably beech) long after the tree was killed from last week's monitoring of a 150 years old mixed woodland.

1. how you come to that conclusion?

2. And in your opinion, should I let the relevant authority know about it, so they may investigate further?

 

1. The tree being a relatively vital Quercus robur and the hoof shape of the perennial FB's partially growing on top of one another.

2. Yes, IMO you should.

Thank you, I shall make the call and see what my very 'efficient' council does about it

Don't know if this has been posted or not, or if the link will work? Interesting read though
