A Cumulative Checklist for the Lichen-forming, Lichenicolous and

Allied Fungi of the Continental United States and Canada

    This checklist 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 are in boldface. Names considered to be synonyms are given in normal font only. Significant changes made since the previous online version are given in blue font. As before, the following symbols are used to indicate the lichenicolous fungi and other allied fungi:

* = lichenicolous fungi (parasites on living lichens)
+ = saprophytic fungi related to either lichens or lichenicolous fungi
# = various 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; or lichenicolous lichens.

    This list is updated at semi-regular intervals, usually about once each year, as changes accumulate in the literature. My purpose for 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 appreciate being informed of any oversights or omissions, and although not all taxonomic or nomenclatural differences of opinion 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 reports in the literature, and their presence here does not necessarily imply endorsement by the author.

    In addition to inviting comments or corrections, it would be very helpful if authors of publications containing additions to the North American lichen biota, or other taxonomic and nomenclatural changes that impact it, would provide me with copies.
