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. Unless otherwise indicated, the text below is derived from the description by Yves Lamoureux in his flicker account here: https://www.flickr.com/photos/27441280@N06/18900114684/. | ||||||||

discussion |
Some comments of YL: In Québec, with the present species,
there sometimes also
occurs another amanita that is smaller with a pale ash-
gray to silver-gray pileus that is uniformly colored.
Unfortunately, we haven't had the opportunity to collect
the latter. In North America, both of these taxa
have been mistakenly identified as A.
vaginata. Translation to English and reformatting for this site is by R. E. Tulloss who is responsible for all errors. | ||||||||

Each spore data set is intended to comprise a set of measurements from a single specimen made by a single observer; and explanations prepared for this site talk about specimen-observer pairs associated with each data set. Combining more data into a single data set is non-optimal because it obscures observer differences (which may be valuable for instructional purposes, for example) and may obscure instances in which a single collection inadvertently contains a mixture of taxa.
