I've searched this board & Google and long wondered the binomial nomenclature for this moss. Appears it's always referred to by it's common name. Does anyone know?

I have found 3 methods for kyoto moss spores and I was wondering what one is the best? 1. Peat tray growth then transfer into tank. 2. Spores into RO water spray bottle and spay into tank. 3. Place into tank and mist with rice water. I guess I could try 2+3 and 1+3. But I wanted to know...
