Taxonomic Corrections and Issues in Arora, D. 1986. Mushrooms Demystified, 2nd. Ed.

by Nathan Wilson, with additions by else c vellinga and other members of the mycology community

This is a work in progress. Please let me know if you have additions. Anyone willing to write explanations about any of these changes, should look up the names on and add the comments to the approporiate page. Let me know if you do that so I can be sure to add a link here to the new page.

The first name is the one that appears in the text.  The second name is the alternative.  Further discussion is available for some of the changes by clicking the lines.

Three classes of changes are indicated by the symbol separating the names:

-> Indicates a widely accepted name change.  In these cases the name in the text is considered synonymous with the alternative and the alternative  takes priority for some reason

<-> Indicates a debatable name change.  In these cases the name in the text is considered synonymous with the alternative, but which names takes priority is debatable.

<-R-> Indicates a regional change. In these cases both names are valid because they actually are different taxa that occur in different regions of the world. The name on the right is correct for the west coast of the United States.

[You may be wondering what happened to the Lepistas. It turns out that the tide has turned back towards those being the true Clitocybes. The issue hinges on what you consider the type species to be. Unfortunately, Clitocybe is a really old genus and doesn't have a clear type. The debate has focused on whether C. gibba or C. nebularis is the type. Now that it has settled on C. nebularis, the genus Lepista is so closely related to C. nebularis that it no longer makes sense to use Lepista. I expect I'll be adding more Clitocybes moving into other genera soon.]
