The main events and people who played a significant role in the increased knowledge of the California mycoflora will be presented. With nice trivia, such as: the collector who collected in more counties than anybody else; the county which can boast the highest number of species discovered as new; and, the connection between Eucalyptus and Mycena californiensis. With special attention to the mycologists of the early 1900s who collected in southern California. All set in the context of worldwide discoveries and developments.
