Amanita franchetii is a species of fungus in the Amanitaceae family. It was given its current name by Swiss mycologist Victor Fayod in 1889 in honor of French botanist Adrien René Franchet.[1] A. franchetii occurs in Europe and North Africa with oaks (Quercus ssp.), chestnuts (Castanea ssp.), and pines (Pinus ssp.).[2]

Amanita augusta, formerly classed as Amanita franchetii sensu Thiers, Point Reyes National Seashore, Marin Co., California, USA

A similar fungus in western North America was also referred to as A. franchetii, but was long suspected of being a separate, undescribed species,[2] and in 2013 was formally described under the name Amanita augusta.[3]

Amanita aspera and Amanita franchetii are synonyms.[4]

There also exists a variety known as Amanita franchetii var. lactella that is entirely white except for the bright yellow universal veil remnants.[5] It is found in the western Mediterranean region, associated with several species of oak (Quercus suber and Q. robur) and hornbeam (Carpinus betulus),[5] and is also reported from Serbia.[6]

Edibility

Amanita franchetii's edibility is suspect; it should not be taken for the table.[7] Although chemical analysis has not thus far revealed in A. franchetii the presence of the amatoxins found in some other Amanitas,[7][8] it has recently been implicated in the deaths of ten people in China who displayed symptoms similar to those caused by amatoxin poisoning.[8]
