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.
- Genera of the Sarcoscyphineae
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.
