Checklist of Amanita Taxa Recorded for the States of  
Alabama, Florida, and Georgia

R. E. Tulloss and Elizabeth Mazzella

In this list of Amanita and Limacella species, there are now 101? taxa of which 40? appear to be undescribed in the literature.

With regard to supraspecific taxa, this document follows this website, "Studies in the Amanitaceae," edited by Tulloss and Yang.

The many collectors who have shared material with the Roosevelt lab are credited on a collection-by-collection basis in the "material examined" data fields of technical tabs for individual species on the "Amanitaceae Studies" website.
Photo credits not given on this page are to be found on individual species pages.

Genus Amanita (The type genus of the family Amanitaceae and identifiable by a sterile gill margin and a cap without gluten.)

Subgenus Amanita (Spores inamyloid.)

Section Amanita (Stipe bearing a basal bulb. NOTE: Do not confuse with cupulate volval remains on nonbulbous stipe base.)

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.)
