1. Amanita franchetii, syntype, protolog plate II (fig. 1a-c), France.
The following is largely based on the description by Neville and Poumarat (2004).
The cap of Amanita franchetii is 65 - 80 mm wide, citrine yellow to yellow, often palest towards the margin, sometimes whitish, hemispheric then convex, finally planar, often rather irregular, sometimes depressed in the center in age, shiny, viscid then silky, not virgate, with an appendiculate margin, sometimes striate in age. The volva is present as small, generally pyramidal warts, sulfur-yellow becoming paler and sordid (for example, pale grayish ochre), easily removable, densely placed. The flesh is 5 mm thick above the stem, white, with a thin yellow region just below the cap skin, tending to turn brown when wounded.
The gills are free at maturity, distant, white, up to 7 mm broad, not or only finely floccose. The short gills are truncate, rounded truncate, or attenuate.
The stem is 65 - 80 × 18 - 20 mm, white, solid, firm, striate above the ring, smooth or
slightly flocculose below the ring, with a napiform bulb up to 33 mm
wide. The ring is membranous, white, striate on the upper surface, with yellow
volval warts on the edge. The volva is present as 2 or
3 incomplete rings of warts at the top of the bulb, at first yellow becoming
yellowish to pale grayish-beige with age. The flesh is white, tending to
turn brown when wounded especially at the base of the stem and the bulb.
The spores measure 7.5 - 9.5 (-11) × (5-) 5.5 - 7 (-7.5) µm and are broadly ellipsoid to ellipsoid and amyloid. Clamps are absent at bases of basidia.
This species was originally described from France but has been reported from much of Europe and northern Africa. This species occurs in the same environments with its form queletii. It is associated with woody plants: oaks (Quercus pubescens, Q. suber), chestnut (Castanea sativa), and pine (Pinus).
Neville and Poumarat accept two forms of the present species in addition to the type form: f. lactella and f. queletii.
The name "A. franchetii" is mistakenly applied to an otherwise undescribed taxon that is commonly found in California. The name "Amanita apera" [for example, see H. D. Thiers (1982)] has also been applied to both the European and North American taxa; however, the latter epithet applies to a lepiotaceous fungus.—R. E. Tulloss and L. Possiel
≡Amanita aspera [var.] franchetii ("Francheti") Boud. 1881. Bull. Soc. Bot. France 28: 91, pl. II (figs. Ia-c). [Misapplication of aspera following Quélet.] [Volva is "jaune citron," and pileus is "jaune souffré très analogue à celle de l’Am. citirina."]

The editors of this site owe a great debt to Dr. Cornelis Bas
whose famous cigar box files of Amanita nomenclatural information
gathered over three or more decades were made available to RET for computerization
and make up the lion's share of the nomenclatural information presented on this site.
