In this list of Amanita species, there are now
95? taxa of which
63? appear to be
undescribed in the literature. A. pantherina
is undoubtedly based on an incorrect determination found in older literature. A few European
species have been found to be in the northern part of the range of this
checklist (for example A. muscaria, A. regalis, and
A. porphyria).
As noted in the bibliography, we had the
privilege of access to unpublished M.Sc. theses of G. J. Breckon and N.
Nakamura and to the Amanita portions of manuscripts of A. H. Smith
The many collectors who have shared material with are credited on a
collection-by-collection basis in the material examined data fields of

Subgenus Amanitina (Spores amyloid. Taxa mycorrhizal)
Section Amidella (Margin appendiculate—at least at first. Volva as a multilayered, thick-limbed, sac on a bulbless stipe base. Many taxa in this section have the unusual combination of amyloid spores with a striate cap margin and truncate lamellae. Species in this section often require microscopic examination for certain identification. A frequent exception is A. whetstoneae. [RET has personal correct field ID rate of around 75%—inadequate.] Many species in this section will stain pinkish (sometimes very briefly) if collected in moist weather or otherwise in very fresh condition. Toxicity of North American taxa of sect. Amidella is unknown.)

Section Validae
(Universal veil almost always friable, appearing as a small limb only in taxa with a
marginate stipe bulb. Stipe always annulate.
Pilei may be brightly colored. Basidia usually rather short and always lacking basal
clamps. While some of the
taxa in this section may not contain a hemolytic compound, a number of them do. Therefore, ingestion of species in this section without
thorough cooking is to be strongly discouraged. Experimentation with eating
amanitas is not a good idea at any rate.)
