"Many of the skills and techniques involved in the isolation, cultivation and identification of mould fungi are more an art then a science. Laboratory procedures considered routine by micologists (scientists who study fungi) seem to be mysterious, well-guarded secrets to the uninitiated. Generally they are passed along from generation to generation of mycologists through a time-honored system of apprenticeship. Access to these skills is difficult for the beginner; most books on the subject are rather advanced and contain such a quantity of information that is not clear where to begin."
