I too have found aquatic magic to be a great company to deal with.
The professor examined the moss and he said it's Hyophila involuta, a moss that can often be found growing on cement walls. The professor also said it is not an aquatic moss and that is probably the reason Bioplast never had great success with it. With most mosses, urban development spells doom but this moss thrives on construction. The more walls are built, the more they are spread around. It's a moss that likes high alkalinity, you see. So if you're one of those die-hard moss lovers who aren't daunted by the fact that this isn't an aquatic moss, raise the Ph of your water if you want them to flourish in your tank. Gan CW, the professor and I are of the opinion that a suitable common name for H. involuta would be "Cement Moss". It's a down-to-earth name for an extremely lovely moss but nevertheless, very appropriate.
