At the last meeting I had bags of mixed mosses. The one we could not identify that had the small leaves is in fact Pearl weed, Hemianthus micranthemoides. A really kind person TPT ID for me.
It grows way to well for me & always have it. Believe it is classed as high light, but 2 WPG our grows very well. I have not shown this to be prone to algae. Makes a thick carpet, wall or mat. I have never planted mine most of it just floats and grows.
