Category B consists of keys that still offer useful information for the identification of species but need to be used alongside current checklists and more up to date keys
Below are all the keys published under the guidance of Dr Jack Marriott from August 1998 till August 2006. One or two of these keys have been updated to be included among the ‘Keys recommended currently’.
Myxomycetes(Corticolous)by David Mitchell
Key to the Corticolous Myxomycetes Parts 1-3 by D. Mitchell (Part I: Bull. BMS 12 (1)April 1978. Part II Bull. BMS 12 (2) October 1978. Part III: Bull. BMS 13(1) April 1979).
Comment: many species are not included so this key could be misleading. There are however some lovely illustrations, which are worth a look.
