Space/Reach: The creature's space and reach—if the creature's space and reach are standard (one 5-foot square and a reach of 5 feet), this line is omitted.
The number listed is the creature's reach. It doesn't say the creatures reach is that number plus the normal amount for a creature of that size - the number is the final, total number.
Not all Huge creatures have a 15' reach as well. Some only have a 10' reach. It depends on if they are considered Huge (Tall) or Huge (Long). Should be a reach chart in the combat chapter of the core rulebook.

I think the GM is misunderstanding something, so I'd start by asking him where he's getting the 15' figure from.
If he says "the space/reach entry", the answer is "thats the space, not the reach". If he says "the creature size and scale table in the CRB", the answer is "hydra are long, not tall". If he says "everything gets the reach listed in addition to <some other arbitrary reach>", ask him to figure out the reach of a great gold wyrm.
Okay, maybe that last is a bit mean.
