Thanks man! In sexual reproduction two mating types are produced so fungi which have both mating types from same mycelium can self-fertile and they are called homothallic. Heterothallic are the ones who have only one mating type from mycelium so can't self-fertile. Furthermore, when we talk about advanced fungi it alludes to fungi that can reproduce in both ways sexually and asexually.
