Cobwebs and spider webs are different things. Spiderwebs are spun from their silk, and you will usuallysee the spider at home in the web. Cobwebs are a mixture of dust and whatever glues the dust together-sorry-I can't be more specific on that part.
Cobweb mold is a fungal growth that appears on plants, mushrooms and even on bare areas of soil. It is characterized by a white or gray, fuzzy appearance on the surface of the soil or plant that very much resembles a cobweb.t is caused by contaminated soil or compost and thrives in high levels of humidity combined with high temperatures. Cobweb mold infestations are serious since the spores reproduce rapidly and will kill plants if not stopped.
