Ganoderma resinacium on interesting oak (loads of photos)

[Will Hinchliffe]

Found 3 Ganoderma resinacium fruitng bodies on an Oak this weekend. Its the first time I have seen G.resinacium in the flesh. Its host was a fantastic Oak tree 24m in height with a 2m DBH. The large diameter is caused by reaction growth compensating for the strength loss due to the internal decay and not indicative of its age. I believe the tree to be about 200 - 270 years old. I do not believe that decay in the main trunk is being caused by the Ganoderma. The decay looked very much like that caused by Laetiporus. I had a dig around the largest of the fruiting bodies and the decay did not seem to extend along the buttress and also appeared to be confined to below soil level.

 

Any way I took loads of photos here they are.

Here is a photo to show I reinstated everything and left the now detatched fruiting body in place. I found two tiny beetles living in the bracket.

Great picture set Will, and I applaud your MO.

 

Can't really tell from the shots, but was there a lateral stem?

It's just that the flesh looks like what I would expect from G. lucidum, but prepared to be corrected on this as I'm not sure.

 

Your flesh shot does seem to show the mid brown concentric zones, that's indicative of as you say resinaceum.

Mmmmm !

 

 

Could you see any brown cubicle inside the Trunk, which would concur with Laetiporus?

The rest of the photo set:

 

1. Some strange grey mineralised soil attached to decaying wood from under the fungi.

2. An adventitious root.

3. Three types of decaying wood found on the floor in the above hole.

4. Bark on the inside of the tree. Re-iteration/rejuvenation ?

5. Inside the trunk

6. Inside the trunk

7. Deadwood in the crown

8. Ganoderma resinacium

There was no obvious lateral stem but when I removed the bracket it did have a single stem like attachment point. The bracket was very dry so may have discoloured. The rot inside was cubicle with visible myceleum in places. You might be able to make it out from the other photos.

Great photos phenom looks like you spent a long time on exploring this tree. IMO looks like laetiporus got there first .
