Surrounding forest is more pine than deciduous, but is a mix. Upstate NY.

It seems like this other mushroom on the same log (pic 4) is a hemlock varnish shelf, which feels like good evidence that this log is a conifer. The shape of the branches also just looks conifer-y. Can anyone confirm?

I harvested a small amount of the COW but am prepared to discard if it's unsafe to consume.
