Nomenclatural revision of F.J. Seaver's North American cup-fungi (operculates)


The following key is interactive and is based on characters that are relatively easily observed. We suggest using it as a way to narrow possible choices when identifying specimens. You will note that following the generic name is the word "character." By clicking on "characters" the scoring for genus will be displayed.

Two additional keys for Phillipsia and Distichophyllum were created using the Java applet "NaviKey" developed in the summer 1997 at HUH. As of January 2002, this software is no longer supported by the Harvard University Herbaria.
