Amanita franchetii, also known as the Franchet's amanita,[1] 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.[2] A. franchetii occurs in Europe and North Africa with oaks (Quercus ssp.), chestnuts (Castanea ssp.), and pines (Pinus ssp.).[3]

A similar fungus in western North America was also referred to as A. franchetii, but was long suspected of being a separate, undescribed species,[3] and in 2013 was formally described under the name Amanita augusta.[4]

Amanita aspera and Amanita franchetii are synonyms.[5]

There also exists a variety known as Amanita franchetii var. lactella that is entirely white except for the bright yellow universal veil remnants.[6] It is found in the western Mediterranean region, associated with several species of oak (Quercus suber and Q. robur) and hornbeam (Carpinus betulus),[6] and is also reported from Serbia.[7]

Description[edit]

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.[8]

Edibility[edit]

Amanita franchetii is considered inedible.[9][10] Although chemical analysis has not thus far revealed in A. franchetii the presence of the amatoxins found in some other Amanitas,[10][11] it has recently been implicated in the deaths of ten people in China who displayed symptoms similar to those caused by amatoxin poisoning.[11]
