I had the same question when I saw them.

I predict they are bitter uncooked and not very flavorful when cooked. But you could prove that all wrong…and they might have a great texture that will soak up good flavors. I am not even experienced with eating the honey mushroom. I will try it someday.

The rhizomorph question… Didn’t notice any on the outside of the cottonwood bark that looked similar to black shoestring rot that is indicative of the honey mushrooms that you mentioned. I am very familiar with that behavior with armillaria when I visit the midwest deciduous forests of Iowa and Missouri(my wife’s family lives in both States). If I encounter more destructive pholiota this season I will look into it a little more intently.


apparently this species is edible- do you have any experience with destroying the destructor for the table? The young buttons looked very similar to Lentinulus idodes(shiitake) to my wife and I and we were tempted to bring some home to try.

You’re welcome Drew!

I noticed that the deprecated name was Pholiota desturens (spelling probably wrong) so I guess it knows how to take down a tree. If it grows that fast, maybe it is related to Armillaria…, does it form rhizomorphs – the bootlace-like bundles of mycelium that Armillaria does?

Thanks Martin!

It was extremely waterlogged from rain- almost tipped over when I picked it off the cottonwood log it was on- by the stem base.

I’ve only found a destructive pholiota once before- near cispus learning center in Randle,WA about 6 years ago- and unfortunately didn’t have my camera with me. These were all fruiting from either side of the log and had nice variations in maturity. Saw the big guy from the the car driving by-it was that friggin huge!

Cool find Drew!

Do you see this often? I can’t imagine a 2 lb pholiota!
