Darryl, From the photos which are taken too far from the weed mass for a good visual, it looks to me that the Chara has a layer of degrading or old filamentous algae intertwined through out the top portion of the Chara canopy. The FA will tend to float at the surface on top of the Chara esp as the water receeds and the weed mass is close to the surface. I have seen similar situations in other ponds.
