See Amanita aspera for a discussion of these names.

9/21/2007 Rod Tulloss said: The version of this name with a single “i” on the end is a misspelling. North American originated observations under the name “francheti” should be listed as “A. franchetii sensu H. D. Thiers” or “A. franchetii sensu western N. American authors”....

9/21/2007 Nathan Wilson said: I noticed that this misspelling didn’t have a synonym link to the correct spelling. With regard to introducing “A. franchetii sensu H. D. Thiers”, I’ll send something out to the mailing list to see if there’s any objection to this.
