February 19, 2018

Taken on the same day as the photograph of the previous post, these photos show Leptothrix discophora and its precipitated iron oxide at Jelks Preserve.

 


Iron Bacteria in Florida 1


My old pal Leptothrix discophora came out to play in the parks earlier this month. This photo was taken in a sweet lagoon of the Venice Myakka River Park.

I saw some Leptothrix discophora films at Schoepfle Garden last month. Here is one patch, with details of the overall photograph beneath.

Sometimes a shadow reveals a less-visible Leptothrix discophora film. Someone explained to me why this happens, but I’m afraid I didn’t quite get it. Perhaps one of you knows and can explain it again?

I found some of what I had come looking for last month when I waded across the river. The first image is the way I saw the patch of Leptothrix discophora film as I approached. It was surprisingly large for such a young film. Young films look blue or silver or silver blue. The prismatic colors arise when the film thickens as a result of more of its being produced by the Leptothrix discophora bacteria or when the film is broken and pieces of it slide over and under other pieces. The second image is the same patch of film seen from the opposite side. You can appreciate the importance of the angle of the sun relative to the viewer in how the film appears.

Strange Mushrooms


October 25, 2016

An expert on mushrooms I’m not, but I do have an interest. I have never seen these little guys. Maybe when they grow up they will look familiar. Here on the pine stump the biggest one is about half an inch in diameter. . . . The more I look at this photograph, the more I wonder if they are puffballs. I’ve never seen pinkish-orange puffballs, and I’ve never seen puffballs growing on a tree stump.
