When hunting turkey tails, I only pick the most prime specimens. Anything rotted I wouldn't use, personally.
A general rule of thumb when using mushrooms gathered from the wild, never ingest without being absolutely 100% positive and double checking.
To me those look like turkey tails. The false turkey tails are indeed non toxic and are also equally as medicinal, and can be used in the same way. I wouldn't go so far as to say all look a likes are non toxic, as I do not know for sure. Just pick the ones you are 100% about and you won't have any problems
