1. Nostoc

   Nostoc, also known as star jelly, troll’s butter, spit of moon, fallen star, witch's butter (not to be confused with the fungi commonly known as witches' butter), and witch’s jelly, is the most common genus of cyanobacteria found in various environments that may form colonies composed of filaments of moniliform cells in a gelatinous sheath of polysaccharides. Nostoc is a genus of photosynthetic, Gram-negative cyanobacteria that can be found in both terrestrial and aquatic environments. It may also grow symbiotically within the tissues of plants, providing nitrogen to its host through the action of terminally differentiated cells known as heterocysts. Nostoc is a genus that includes many species that are diverse in morphology, habitat distribution, and ecological function. Nostoc can be found in soil, on moist rocks, at the bottom of lakes and springs, and rarely in marine habitats. It may also be found in terrestrial temperate, desert, tropical, or polar environments.The name Nostoc was coined by Paracelsus and is a combination of the English nostril and German Nasenloch "nose hole, nostril", likely due to appearance of many species colonies being similar to nasal mucus. When it is on the ground, a Nostoc colony is ordinarily not seen, but after a rain, it swells up into a conspicuous, jellylike mass, which was once thought to have fallen from the sky, hence the popular names, like star jelly, troll’s butter, and witch's butter mentioned above.

1. nostoc

   Nostoc is a genus of cyanobacteria that forms colonies composed of filaments of moniliform cells in a gelatinous sheath. These colonies may form slimy masses in soil, water, or even living plant tissues. They typically appear when moisture is abundant, and might be single or form colonies. Many species of Nostoc play a significant role in fertilizing soils by fixing nitrogen from the atmosphere. They are also used as a food source in certain cultures and are sometimes found in dietary supplements due to their high protein content.

1. Nostoc

   Nostoc is a genus of cyanobacteria found in a variety of environmental niches that forms colonies composed of filaments of moniliform cells in a gelatinous sheath. The name Nostoc was coined by Paracelsus. It derives from the ancient Greek word "nόsos". Nostoc can be found in soil, on moist rocks, at the bottom of lakes and springs, and rarely in marine habitats. It may also grow symbiotically within the tissues of plants, such as the evolutionarily ancient angiosperm Gunnera and the hornworts, providing nitrogen to its host through the action of terminally differentiated cells known as heterocysts. These bacteria contain photosynthetic pigments in their cytoplasm to perform photosynthesis.
