A new type of secondary mutation at the Bβ incompatibility locus of Schizophyllum commune is reported. The secondary mutation Bβ7(1–4) was induced by X‐rays from the primary mutant allele Bβ7(1). The mutant Bβ7(1–4) allele showed an exceptional pattern of interactions with wild Bβ alleles, which normally behave as though they are completely equivalent and uniform in their mating interactions with other wild alleles and with mutant alleles of the locus. The new Bβ mutation is compatible with three wild Bβ alleles and incompatible with four wild Bβ alleles.
