The filamentous fungus Chromocrea spinulosa (Trichoderma spinulosum) exhibits both self-fertile (homothallic) and self-sterile (heterothallic) sexual reproductive behavior. Self-fertile strains produce progeny cohorts that are 50% homothallic. 50% heterothallic. Heterothallic progeny can mate only with homothallic strains. https://www.lasreglasdejuego.com/product-category/hydrating-cream/
