Hello, No I did not eat it.

I have found H. erinaceus near by where I found this specimen and there is a big difference in consistency. H. erinaceus forms in one consistent ball with little separation at all but the H. americanum is broken into separate sections by branches with the teeth forming nodes at the end of the branches as in my previous observation.
Here is my observation of both Hericium erinaceus and Hericium coralloides for comparison.

Your previous observation looks more like the erinaceus than recent ob. Did you eat it?

This was a week specimen.

But if you look at the specimen I found last year growing out of the same log you will see it has branches with nodes at the end as in Hericium americanum.

The icicles look clumped and very long. I’ve seen cultivated ones that looked like yours, I think they didn’t properly develop.

I know that Hericium americanum is said to only be found on the east coast but the teeth length and branching makes it the only option. See my observation from last year.
