that Jason gave the same classification to this specimen and to the one in observation 98195. I think this cannot be, because the thallus have different consistency, this one is thin and the other is thick, the underside are also quite different. The chemical reactions were also different: the KC+ reaction of this one was initially red and fades to something undefinite, whereas the other one preserved the yellow-red reaction.

was even stronger than the captured in the photo, since it fades a bit.
Thanks, jason, for the proposal.
