My best guess is that the substance on these branches is 'Trentepohlia', a genus of filamentous green chlorophyte algae which lives on tree trunks and wet logs. The strong brownish-orange color of the filaments, which mask the green of the chlorophyll, is caused by the presence of large quantities of carotenoid pigments. I discovered this algae growing on top of a high bluff next to the Pacific Ocean in northern California.

"Algal and cyanobacterial blooms can grow in fresh water, salt water, and brackish water (a mixture of fresh and salt water) around the world, including in water people use for drinking or recreation. Harmful blooms tend to form in warm water with high levels of nutrients such as nitrogen and phosphorus."
This was adjoining a farmyard where these chemical concentrates probably leaked from.

This almost fluorescent orange algae thrives in this part of the North Island -- it's all over. It was hard to get a good photo of, but this at least gives an idea. It was also hard to ID! Didn't help that it was identified there as a type of "brown algae", which I took to mean Phaeophyta -- that turned out to be a dead end. A brute-force Flickr search on "New Zealand algae" finally turned up a photo labeled with an ID. It turns out to be botanically a type of green algae (Chlorophyta) called Trentepohlia.

The absolutely cutest underwater organisms are the young squids, octopuses, and cuttlefish. We startled this one out of the macro algae blanket. It popped up into the water column and inked my dive buddy twice then sat in the light beam of his canster light and let me (try) and get a couple good shots of him. HARD to do macro on a tiny 1.5cm long critter jerking back and forth in the water (changing depth too) with no focus light or flash. Fortunately a coule turned out….This one is a bit soft all over and the depth of field was way too short. The focus is actually a bit in front of the squid. Argggh. But you can also see all the shmutz in the water. Making it even harder to focus, as the auto focus kept trying to focus on th shmutz. Much of it is actually small copepods.

the water at low tide looks in a disgusting state. Environment Agency have told me that it's decaying algae, Phaeocystis, NOT sewage. It's non poisonous, but is messy. You can download a document from the Environment Agency website about marine algae at www.gov.uk/government/publications/marine-algae-advice-fo...

Algae from pond water. Photo taken with Zeiss PMII scope 16x plan objective and Canon EOS 60D camera equipped with Zeiss 47 60 10 intermediate tube and Leitz 4x projection lens. Modified brighfield. May be Closterium
Enjoy the pretty soothing colors.... *drool*

This algae is called coralline because it forms a hard calcium structure by accruing calcareous deposits within its cell walls.
See this picture www.flickr.com/photos/jrosenk/5035561928/ to get an idea of how these algae use a crustose form to adhere to the rock in the tidepools
Watch THE MOVIE! I made of the things I observed this day!
Are these springtails? I found them on rocks and on ice around the shore of Lake Ontario, Canada. It seemed like they were walking on water but I think there may have been a thin sheet of ice that I couldn't see. You can see what I mean in the video during the clip of the earth worm in the water. They are also hard too shoot because they are so active. Constantly crawling around or jumping at light speed. (maybe a little faster) It looks like they have very short wax secretions.

About the video:
This is a collection of video clips I took one day. I was photographing algae with my new macro lens and noticed all kids of things moving around in the cold water. The lake is still frozen over, yet these insects and little creatures have adapted to the extreme temperatures. I also made the music. I used reason to make the drums and garage band to record the dulcimer and some vocals as well as adding fx. The song isn't done yet but it's coming along nicely.

parasitic algae are not the norm. The only species that is common in the United States is Cephaleuros virescens. It causes a disease called algal leaf spot - hgic.clemson.edu/factsheet/algal-leaf-spot/

I am trying to create a algae bloom with very minimal resources. On
the left is a old glass jar with some recently harvested algae from
our hot spring drain. On the right is a mixture of sugar and yeast
with some hot spring water which I am trying to generate CO2 with to
send over to the algae.
Amy Hamilton, a biologist with the Maryland Department of Natural Resources, collects a sample of algae and bay grass from the Susquehanna Flats near Havre de Grace, Md., on Aug. 2, 2019. Hamilton was attempting to identify the presence of Lyngbya, a type of algae that can form harmful algal blooms in the Chesapeake Bay. (Photo by Will Parson/Chesapeake Bay Program)
