A. franchetii (Boud.) Fayod var. franchetii
Amanita aspera var. franchetii Boud.
Amanita franchetii, also known as the Franchet's amanita, is a species of fungus in the family Amanitaceae. It was given its current name by Swiss mycologist Victor Fayod in 1889 in honor of French botanist Adrien René Franchet. A. franchetii occurs in Europe and North Africa with oaks (Quercus ssp.), chestnuts (Castanea ssp.), and pines (Pinus ssp.).
A similar fungus in western North America was also referred to as A. franchetii, but was long suspected of being a separate, undescribed species, and in 2013 was formally described under the name Amanita augusta.
Amanita aspera and Amanita franchetii are synonyms.
There also exists a variety known as Amanita franchetii var. lactella that is entirely white except for the bright yellow universal veil remnants. It is found in the western Mediterranean region, associated with several species of oak (Quercus suber and Q. robur) and hornbeam (Carpinus betulus), and is also reported from Serbia.
The cap is 5–12 cm wide, and is yellow-brown to brown in color. The flesh is white or pale yellow, and has a mild odor.
Amanita franchetii is considered inedible. Although chemical analysis has not thus far revealed in A. franchetii the presence of the amatoxins found in some other Amanitas, it has recently been implicated in the deaths of ten people in China who displayed symptoms similar to those caused by amatoxin poisoning.
