Grifola frondosa.

[David Humphries]

Cherry with Grifola from earlier in this thread.

Fruiting has occurred regularly on both sides of the buttress root that has the obvious girdler.

 

 

had the chance to run the airspade over the target area today to have a closer look and to sound the roots with a nylon hammer.

 

 

We found that there were a significant number of Armillaria rhizomorphs all through the rooting zone, we suspect these (due to their size and vascular condition of the tree) to be of a more benign species of Armillaria, possibly A. gallica

 

 

On further inspection we found that the majority of the roots around the Grifola fruiting sites are in good sound vascular working order.

 

 

We'll continue to monitor the trees condition

Greetings! I'm not an arborist, but found this thread after asking for help in a local environmental group on FB.

 

I have a large white oak tree that has been losing more and more leaves every year for a few years. I thought this was just a sign of age and the tree was approaching the end of its life. However, I recently learned trees can have a fungus, and immediately recognized the Grifola Frondosa from pictures. My oak gets this "Hen of the Woods" growth every year for the last 6-8 years and embarrassingly I never associated the fungus with the leaf loss/dying branches.

 

So, my question is how do I find a local arborist (I'm in Baltimore, MD) that is well-versed in this type of fungus on White Oaks to be able to give us guidance on what to do? If the tree is becoming unstable, it is definitely a potential safety issue as it's within reach of our house and our neighbors.

 

I hate to lose this tree if it's not a safety issue, but am not sure what to do. Any guidance would be greatly appreciated. Thank you!
