| 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 from the protolog of the present taxon. | ||||||||||||||||||||||||||||||||||||||||||||

| discussion | This species contains genes for amatoxins, but it is widely eaten (in some regions) to no ill effect. The authors of the species conclude that while the genes are present, for some reason, they are not expressed. | ||||||||||||||||||||||||||||||||||||||||||||
