Observation 24939: Amanita caesarea group

When: 2009-08-16

Collection location: Guadalajara, Jalisco, Mexico [Click for map]

Who: Alan Rockefeller (Alan Rockefeller)

Specimen available

This is the one they call Amanita caesaria in Mexico. The first one found was an older specimen, a few minutes later we did manage to find some nice ones. The season for these was just ending at this point.

This species grows with Oaks, but not the Oaks with the huge leaves.

One was eaten and it was delicious. The other was saved for Rod Tulloss.

I’ll be very interested to see the material that was not eaten.

All of the taxa named by Guzman and Ramirez-Guillen were described as red. I suppose you judged these to be sun-faded specimens.

Very interesting. You should be aware that Amanita basii is also called “caesarea” in Mexico. In fact, I think that all the taxa named by Guzman and Ramirez-Guillen have been called “caesarea” somewhere in Mexico. Recent DNA studies suggest that all Mexican, red taxa of stirps Caesarea that were sampled were distinct from caesarea at species rank.

Very best,
