Scaly wood mushroom Potential lookalikes

Other members of the Agaricus family look similar, to help single out others in this genus you can work through this check list.

  • Most important is no yellow staining (this eliminates the poisonous Agarigus)
  • Strongly stains red
  • In woodland
  • No chemical smells ( very likely poisonous)

The Agarigus sylvaticus is very similar but also edible, it has a slightly slimmer stem and prefers conifer woodland. 

There are a couple of similar mushrooms not in the Agaricus family, Psathyrella maculata and Psathyrella cotonea which look very similar, are your unlikely to come across them as they are rare but a distinguishing feacher is they do not stain red.
