Sorry, no ID threads. Read the rules, the people above tried to inform you of this, which is also help being offered even if you were expecting it in another form.
We cannot and will not identify a drug for you based purely on how it looks. This can give a false sense of security and is speculative. People saying that they have or have not encountered mushrooms that looked vaguely or very similar is not proper identification.
If you do not know whether to trust them, start with an extra low dosage if you decide to proceed... if you do not want to take any risk, don't eat them. Simple as that.
You can grind the mushrooms into a powder if they are cracker-dry, that will make the batch you have into a more evenly distributed potency so that you can measure doses more reliably.
Try to get a scale to get an idea of how many grams you are eating, if you don't already have one.
