discussion |
This species was discovered during a genetic survey
of the Roosevelt herbarium. At present the
species is known from Missouri and New Jersey. The material involved was originally classified in A. wellsii. The latter species has a known range in northern North America extending from Michigan to northern Québec to subarctic heath on the Island of Newfoundland and southward to Pennsylvania.—R. E.

intro |
The following text may make multiple use of each data field. The field may contain magenta text presenting data from a type study and/or revision of other original material cited in the protolog of the present taxon. Macroscopic descriptions in magenta are a combination of data from the protolog and additional observations made on the exiccata during revision of the cited original material. The same field may also contain black text, which is data from a revision of the present taxon (including non-type material and/or material not cited in the protolog). Paragraphs of black text will be labeled if further subdivision of this text is appropriate. Olive text indicates a specimen that has not been thoroughly examined (for example, for microscopic details) and marks other places in the text where data is missing or uncertain. The following material is based on phogographs and notes of collectors, molecular studies supervised by Dr. Joszef Geml (Leiden) and Stephen Russell (Purdue). | ||||||||||||||||||||

discussion |
The present species is genetically separable from
A. wellsii to
which the reader should make a comparison. When
the present species was first collected it was
mistaken for A. wellsii. We do not know if the species have distinct and separate ranges. At present, A. wellsii seems to have a more northerly distribution—extending, at least, from Michigan to New England and Pennsylvania to northern Quebec to subarctic heath on the Island of Newfoundland. On the other hand, collections of the present species extend from Missouri to the inner coastal plane north of Princeton, New Jersey. The range is likely to be greater. It may extend into other montane areas of the south and up the eastern coast to Long Island, New York, and Cape Cod, Massachusetts, where a number of other "southern" amanitas are known to occur. Additional information about range and habitats of both taxa will be valuable. | ||||||||||||||||||||
