Alan, I will review my notes and see if I can come close to a section within Telamonia, but Mexican material, brother – we have some of that floristic group in Calfiornia – it is off the charts. Dna only speaks here. Otherwise I can tell you some name, but it very unlikely that it will be true.

I have to put page of the Mexican influenced Corts, Russula and Amanitas in our area based on environmental samplings from Mexico… It is fascinating.
