Wall analyses on recently isolated strains of Willoughby's ‘spore‐dome’ actino‐mycetes grown in submerged culture would suggest that the peptidoglycan contained ll ‐diaminopimelic acid ( ll ‐DAP) or meso ‐DAP or even mixtures of the two isomers. This chemotaxonomic paradox was explained when it was shown that the vegetative mycelium had walls containing ll ‐DAP and glycine (wall chemotype I) and that spores contained only meso ‐DAP as the diagnostic amino acid (wall chemotype III). Our earlier data had been obtained from preparations derived from biomass containing mixtures of spores and vegetative mycelium.
