Downriver Walk 2015—Still More Leptothrix discophora
November 9, 2015
Sometimes a Leptothrix discophora film can look colorful but very shear, very translucent. Why? I don’t know. (For that matter, I don’t know why some of the L. discophora films look opaque.) The first photo shows what I mean. The other four photographs show a film where much or all of the water has run out from underneath it as the river recedes from the bank so that the film rests on rocks or soil.
