For the player
Lagerophonist, lagerphonist and lagophonist. I prefer not to take sides on this one apart from floating the thought that perhaps euphony should decide. But I would be willing to publish a popularity poll if anyone wants to tell me their choice. Incidentally Leonie Dettmann in sunny Queensland has suggested 'carton' as a suitable collective. I rather like that.
