Checklist of Amanitaceae of Pacific Coastal States and Provinces: Alaska to Baja California del Norte Including Idaho

Please notify RET in cases of broken links! Thank you.

In this list of Amanita species, there are now 100? taxa of which 45? appear to be undescribed in the literature.

Reports of A. pantherina are undoubtedly based on an incorrect determination found in older literature.  Amanita phalloides is considered an introduction to the region of interest from Europe with imported oaks and nut trees.

A few European species have been found to be in the northern part of the range of this checklist and may have holarctic distribution (for example A. muscaria, A. regalis, and A. porphyria).  Amanita alaskensis is known to occur in northern Europe, where some mycologists hold that it is A. friabilis.  Other European mycologists have tried to obtain the argument justifying this view, but (at the date of the most recent revision of this list) an answer has not been forthcoming.

As noted in the bibliography, we had the privilege of access to unpublished M.Sc.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 technical tabs for individual species on the Amanitaceae Studies website (here).  Photo credits not given on this page are to be found on images tab of individual species pages.

The background photo is by Ronald Pastorino and was taken in November, 2015 in the Trinidad State Beach area north of Eureka, California.

With regard to supraspecific taxa, this checklists follows (Corner and Bas, 1962), (Bas, 1969), and (Gminder, 1994).

Subgenus Lepidella (Spores amyloid.)

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 the eastern US species, 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.)
