Checklist of Amanitaceae Recorded for Northeastern U.S. States

R. E. Tulloss, Mary Macher, and Elizabeth Mazzella

This checklist covers the species of Amanitaceae recorded in literature or on the present website from the U.S. states east of Ohio and north of Pennsylvania and New Jersey.  The checklist presently contains 123 species of Amanita and two species of Limacella.  The authors are still in the process of proofing the text and adding images.

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.  [RET has personal correct field ID rate of around 75%—inadequate.]  A frequent exception is A. whetstoneae.  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.)

    All specimens of this species collected to date have been small with a submembranous univeral veil in patches on the cap.  Otherwise, this species has been distinguished from other rubescent amanitas genetically.  Spores: [60/3/1] (6.5-) 6.9 - 9.5 (-10.5) × 4.5 - 6.1 (-7.0) µm, (L = 7.7 - 8.7 µm; L' = 8.1 µm; W = 5.1 - 5.6 µm; W' = 5.3 µm; Q = (1.27-) 1.36 - 1.70 (-1.80); Q = 1.49 - 1.54; Q' = 1.52).  [ image ]

    Spores: [406/19/16] (6.3-) 7.0 - 9.8 (-13.3) × (4.5-) 4.9 - 6.6 (-8.4) µm, (L = (7.2-) 7.8 - 8.8 (-8.9) µm; L’ = 8.4 µm; W = (5.2-) 5.5 - 6.2 µm; W’ = 5.7 µm; Q = (1.18-) 1.25 - 1.67 (-2.02); Q = (1.32-) 1.36 - 1.56 (- 1.64); Q’ = 1.47).  [ image ]
