Field Notes
I was happy because we were going to try and find out if there was rock snot in the stream behind the school. I saw rocks, running water, trees, railroad tracks. I heard running water and animals making noise. I could smell pine from the pine trees. I was surprised that we didn't see any rock snot. I couldn't get a good picture of the rock at first because of the suns reflection.
Supporting Evidence

The Rock snot is supposed to look slimy in the water, and feel like wet wool.

Didymosphenia geminata was NOT FOUND

I agree. With a name like SmartyPlants, I'll defer to your judgement!

The photo of the stream you visited shows a habitat that's ideal for rock snot. If I were on safari for didymo, I'd look just where you did.

And you've nailed its description--slimy in appearance but somewhat gritty (like wet wool) to the touch.

If possible, keep looking for didymo in this particular stream. One question to ask is this: "how's the fishing?" Didymo travels on fishing boots and waders, so if it this stream is popular with trouters, it's a good candidate for rock snot invasion.

Thanks for looking! --Paul

Didymo

Thank you, and your welcome! Our teacher said that people do fish in that brook. We will try to check again, if possible.
