A Cumulative Checklist for the Lichen-forming, Lichenicolous and

Allied Fungi of the Continental United States and Canada

This list consists of cumulative updates to the most recently published North American checklist by Esslinger and Egan (1995). The style and conventions for listings used there are also generally followed here. As in the published checklist, under each genus the accepted names are given first and in boldface. The list of synonyms for each genus follows the accepted names, but here they are underlined instead of being in italics. Essentially all changes, additions or corrections made since the 1995 publication, even if only minor changes in spelling, are presented in blue in order to draw attention to them. As before, the following symbols are used for the lichenicolous fungi and allied fungi:

* = lichenicolous fungi (parasites on living lichens)

+ = saprophytic fungi related to lichens or lichenicolous fungi

# = various related fungi of uncertain status: i.e., those which are questionably or weakly lichen-forming; or algicolous/saprophytic; or parasitic when young but saprophytic or lichen-forming when mature.

My intent is to update this list at regular intervals, at least once or twice each year, corresponding to my completion of the most current Recent Literature on Lichens for The Bryologist. The purpose of putting this checklist on-line is twofold. First to provide users of the checklist with the most current updates and changes, and second to provide the opportunity for (indeed, to invite) comments and suggested corrections from all users and readers. I would especially appreciate being informed of any oversights or omissions, and although not all differences of opinion regarding the taxonomy or nomenclature will be easily or immediately settled, any matters regarding such opinions that users would like to share will be welcomed and taken under consideration. Additions or changes appearing in this on-line version of the checklist represent what has been reported in the literature, and their presence here does not necessarily imply acceptance, tacit or otherwise, by the author. Some of these changes will likely be changed again before another hard copy of the checklist is published. Please send comments to:

Suggestions For Use: Presently this web site consists of one large file, and, depending upon your type of connection to the internet, it will take anywhere from a few seconds to a minute or two to load onto your computer. Once loaded, use of the below letter menu and the internal "Return To Menu" hyperlinks allows movement within the document very efficiently with most web browser software. Use of the "Back" function provided by most browsers usually works fine, but sometimes causes problems, at least until the internal hyperlinks have been used the first time.
