The Rego Mentem spell guidelines don't mention that summoning a ghost has to be a ritual, but the spell description does. Now that we have clarification from the person who wrote the rules, we should conclude that the spell guidelines, not the spell description, are in error. Summoning a ghost should always be a ritual.
