Amanita xylinivolva

This species looks very close to Amanita xylinivolva. I know the latter occurs in the central volcanic zone of Mexico. Michoacan is S-SW of the areas I have collected in in Mexico. Amanita xylinivolva occurs with oak as the probable symbiont in Costa Rica and Colombia. In Mexico, it may also occur in mixed forests with conifers.

The species appears to have a relatively large N/S range, and is rather common in the Chiricahua Mountains of SE Arizona, USA.

Very best,
