Richard Korf is an important gure in the study of discomycetes. His contribution as teacher and scholar in relationship to Boudier’s masterwork, the Icones Mycologicae, is commented upon particularly in regard to the classi cations used for the Pezizaceae. Although it has been common practice to recognize a single genus Peziza for most of the species in the Pezizaceae, molecular phylogenetic studies have shown that the genus Peziza is diverse and is not monophyletic. Boudier’s classi cation shows a more accurate pic- ture of the diversity within the family than later classi cations. Comments on the Icones and Cooke’s Myco- graphia are included as they relate to graduate training and opportunities o ered by Richard Korf in his long career as a teacher.
