Nostoc is a dark blue-green, jelly-like organism sometimes found in soggy home lawns. While the organism’s discovery can be alarming for homeowners, it causes no harm to plants or animals.
How do you get rid of jelly fungus?

How do you treat Nostoc?
Although Nostoc is not technically a type of algae, herbicides labeled for moss and algae are often the most effective at killing Nostoc. It is best to apply the herbicide when the lawn is dry. Be careful to follow the directions carefully to avoid damaging the surrounding turfgrass.
Is Nostoc harmful to humans?
Among the photosynthetic microorganisms, cyanobacteria, belonging to the genus Nostoc are regarded as good candidate for producing biologically active secondary metabolites which are highly toxic to humans and other animals.
How do I get rid of slime mold in my garden?
Slime molds thrive where conditions are moist, so the easiest way to remove it is to let the area dry out. Rake up slime molds in garden mulch to expose the organism to drying air. You can also just scrape up the stuff, but likely it will be back.
Is slime mold harmful to plants?
The gross-looking substance known as slime mold shows up on mulch and lawns, but is harmless to plants. Instead it feeds on decaying matter, fungi or bacteria, according to Neil Bell, a horticulturist for Oregon State University Extension Service.
Where is Nostoc algae found?
Nostoc can be found in soil, on moist rocks, at the bottom of lakes and springs (both fresh- and saltwater), and rarely in marine habitats. 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.
How does Nostoc reproduce?
Nostoc reproduce vegetatively or asexually by spore formation. The vegetative reproduction is by fragmentation. Small colonies can grow attached to a large colony and later form separated colonies. Asexual reproduction is by the formation of resting spores known as akinetes.

What does seaweed look like in the ocean?
Some forms of seaweed look like long strands and branches. Seaweed is a microorganism that grows in oceans, lakes, rivers and other bodies of water and is comprised of algae. Algae is a plantlike organism that doesn’t contain actual roots, flowers, leaves and stems, but does contain the green pigment known as chlorophyll.
What kind of algae looks like green slime?
Cyanobacteria like Nostoc used to be called blue-green algae, but it’s now known that they are not algae at all, though they perform photosynthesis the way algae and plants do. So although Nostoc looks like some kind of green slime algae, it’s actually some kind of green slime bacteria.
What happens if you leave seaweed in garden too long?
If you leave the seaweed in the sacks too long, it gets sludgy and slimy, and is more difficult to spread evenly over the soil. Spread the seaweed thickly and evenly around the garden beds to cover any exposed soil. You may think you’re adding too much, but in a few days you will think otherwise.
What kind of seaweed can I use in my garden?
