You can put a drop of 5% or 10% KOH solution (in water) on the cap. If it turns yellow, then you have support for the identification of the species as A. bisporigera. Sam asked if I would look at dried material. Yes, I will look at material that is mature enough to make a spore print. I would not ordinarily solicit material of bisporigera. In this case, you have a project is interesting. Poison content varies greatly in A. bisporigera according to past reports, from nearly nothing to more than enough to kill an adult human.
