I think the reminder text is correct, but just making sure.

Mutate (Pay mana equal to this creature’s toughness: Put a +1/+1 counter on this creature. Mutate only as a sorcery.)
Each creature you control with a +1/+1 counter on it has reach.
Reminder text doesn't have to be exact, it isn't rules text, but Pay mana equal to this creature’s toughness feels too ambiguous. It might read better as (X X is this creatures toughness:Put a +1/+1 counter on this creature. Mutate only as a sorcery.) Honestly while it clears up ambiguity it looks ugly as heck.
Seems okay to me for reminder text. I think the actual rules might only need to be just a little longer "Pay an amount of mana equal to this creature's toughness".

The problem is there is no exact precedent for it. Elemental Resonance is producing mana that is equal to another amount of mana. Nykthos is producing an amount of mana equal to a nonmana number. Nykthos is probably a bit more similar to this. The distinction, to me at least, looks like the difference between mana cost (an amount of mana) and converted mana cost (a number).
There is also tye recent Confiscation Coup which uses "pay an amount of E equal to" to convert a number (the converted mana cost of the targeted creature) into an energy cost.

Is that indeed proper? If it is, I'd like for that to be the reminder text. Is it Nykthos, Shrine to Nyx or Elemental Resonance?
