FFF, very fertile; F, fertile; St, sterile. AS differentiates both Anneaux and Secteurs and synthesizes α and σ only in the respective modified areas. As* differentiates Anneaux but not Secteurs, though they have the σ determinant throughout the mycelium; As differentiates Anneaux but not Secteurs and never contain the σ determinant; a*S differentiates Secteurs but not Anneaux, though they have the α determinant throughout the mycelium; aS differentiate Secteurs but not the Anneaux and never contain the α determinant.
