Dr. Theodore L. Esslinger of North Dakota State University's Department of Botany provides this website, which contains cumulative updates to the 1995 North American checklist by Esslinger and Egan. This extensive taxonomic list of lichenicolous and allied fungi (i.e., parasites living on fungi, saprophytic fungi, etc.) covers taxonomy and nomenclature for known species in the Continental US and Canada. Originally published in 1995, this online update highlights all new changes in a different color--a handy feature that allows the user to document scientific progress in the field. The checklist is organized by genus and is alphabetically ordered.
