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.Bojantchev D, Davis RM. (2013.) Amanita augusta, a new species from California and the Pacific Northwest. North American Fungi 8(5):1-11. 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.

A DNA barcode is a short, standardised stretch of genes that works like a fingerprint — enough to tell one species from another. Below is the molecular trace Amanita franchetii has left across the world's sequence archives.

How to read this: each dot is one detection of this species' DNA in an environmental sample. The confidence meter weighs how many independent studies and places back up the signal — one detection in one study is a hint; many across several studies is solid. Records dated before 2008 (when eDNA methods began) are treated as likely mislabeled and left off the map.
