The Bloomin Algae app allows users to submit photos of potentially toxic algae, allowing authorities to assess any risks. Download links available via www.ceh.ac.uk/news-and-media/news/bloomin-algae-new-app-h...
This is the only plant disease I know of that is caused by an alga. It attacks magnolia, mango, avocado, citrus, guava, and other Florida trees. This one is on a leaf of Magnolia grandiflora.

Since many of the blue green algae are using chlorophyll A and B I
can give them the same light wavelengths that I would give to a
plant. Here you can see my 20W LED pizza pan setup being used to try
and help the algae grow. Normally I would just put the algae outside
and not waste the electroncs, but it has been dark and stormy today.
Some species of algae have evolved to grow in small pockets of meltwater found on/in bodies of snow. Seen here as specks and paint-like blobs of goop are flourishing colonies of the common alpine alga, Chlamydomonas nivalis.
For the record I stuck my finger in it and used the goop to finger paint on the adjacent rocks.

After a month, and after adding high powered actinic and metal halide lamps to our tank (plus a 12-LED blue "moonlight system), we finally got the desired algae bloom. The snails, hermit crabs, featherdusters and various anemones are thriving, and we have a good population of small buggy critters, also highly desired. The snails are laying eggs, the Aptasia are thriving (perhaps to our regret, later) and we've even got some broad leafed algae that looks very nice. The tank has cycled twice (nitrogen) and everything is staying in bounds - ammonia, nitrates, nitrites. Now for some patience...
I clipped the tank out of this image, annotated and color balanced it, you can see it here.
Green algae covered boulders dominate this rocky coast scence. The high tide line can be seen at the top of some of the boulders. California, Bodega Bay area.
