The first edition of these keys was published in the _Bulletin of the
British Mycological Society_ 2, 18-43 (1968) and 3, 86-88, 121-124 (1969)
in an attempt to bring together in one place information for the
identification of coprophilous fungi which would be useful to teachers
and others interested in these fungi. They were issued as a separate
publication in 1972, and with corrections in 1974. They were reprinted in
1982 with additions. This latest edition is an update of all the earlier
ones, with current nomenclature and recent references, and the inclusion
of some additional species.
