Abstract
A spontaneous spore-colour mutation located in the gene b2 of A. immersus gives a high frequency of reversion. 8 distinct revertant phenotypes have been defined. The mutations corresponding to these revertants are located at the same site or very near the original mutation. The hypothesis that the mutation by itself is responsable for the observed reversions is advanced.
