Mougeotia viridis algae undergoing sexual reproduction (conjugation) by producing zygospores. 40x Objective. From boggy area in acidic heath.
Modern land plants evolved from algae living along with aquatic animals as represented in this 1930 illustration by Brooklyn Botanic Garden’s staff illustrator Maud Purdy.
We usually suffer from blue-green algae in the heat of summer, but it's autumn now and quite cool. Must be a lot of nutrients in the lagoon.

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. Sharpened image of Algae 18A
The clarity on this is better and the color more apparent on this snail. You can see the cross fibers of the algae growing on the window of the tank (and here I thought i just cleaned it...if you can see this imagine what you kitchen table would look like under a microscope...)
This guy is about .5 centimeters in real life
this single swan was in a small rivulet completely covered in green algae, as you can see from its beak
Because of their calcified structure, coralline algae have a number of economic uses. The collection of unattached corallines (maërl) for use as soil conditioners dates to the 18th century. This is particularly significant in Britain and France, where more than 300,000 tonnes of Phymatolithon calcareum (Pallas) Adey & McKinnin and Lithothamnion corallioides are dredged annually. Some harvesting of maërl beds that span several thousand kilometres off the coast of Brazil takes place. These beds contain as-yet undetermined species belonging to the genera Lithothamnion and Lithophyllum. Maërl is also used as a food additive for cattle and pigs, as well as in the filtration of acidic drinking water.
The earliest use of corallines in medicine involved the preparation of a vermifuge from ground geniculate corallines of the genera Corallina and Jania. This use stopped towards the end of the 18th century. Medical science now uses corallines in the preparation of dental bone implants. The cell fusions provide the matrix for the regeneration of bone tissue.
Since coralline algae contain calcium carbonate, they fossilize fairly well. They are particularly significant as stratigraphic markers in petroleum geology. Coralline rock also functions as building stones, with the best examples being in Vienna, Austria.
