What is the life cycle of the Myxomycetes?
The myxomycetes have an interesting life cycle which includes a wet spore phase and a dry spore phase. When conditions are favorable, they move about like amoebae, resembling primitive animals. When conditons are not favorable they form a resting body (sclerotium) with dry, airborne spores.
What is the difference between windwind and myxomycetes?
Wind disperses the dry fruiting body spores, whereas the wet amoebic phase is motile. Occasionally found indoors. None known. The myxomycetes have an interesting life cycle which includes a wet spore phase and a dry spore phase.

Is slime mold a Myxomycetes?
Slime molds are fungus-like organisms that have previously been classified as fungi, but they are no longer classified as fungi. Depending on the sources, there are now two or three different groups of slime molds, one of which is the Myxomycetes. These now fall under the broader category of eukarya.
Is Stachybotrys toxic?
This mold may cause human disease through direct irritation, type 1 hypersensitivity or the production of toxins. A variety of respiratory, dermatological, eye and constitutional symptoms have been associated with heavy and prolonged exposure to S chartarum.
Why are Myxomycetes called slime molds?
Myxomycota. Members of this division are commonly referred to as slime molds. Although presently classified as Protozoans, in the Kingdom Protista, slime molds were once thought to be fungi (=kingdom Mycetae) because they produce spores that are borne in sporangia, a characteristic common to some taxa of fungi.
Should I remove slime mold?
You also can just wait it out, and it should go away on its own. Remember, since slime mold isn't dangerous, you don't want to use toxic chemicals that could pose a threat to children, pets, plants, or the environment.

What is a myxomycetes?
Myxomycetes are fungus-like organisms that reproduce using spores. Separate from fungi, myxomycetes are macroscopic slime molds that feed on dead plant and animal material. Common in places like lawns and forest floors, they are also found in tropical areas, fruits, and tree canopies. Anywhere there is decaying biological material in adequate quantity, there will most likely be myxomycetes.
How big are pseudocapillitium spores?
Then there are the actual spores, the heart of everything. They can range in size from 5 to 15 micrometers. Almost all of them are round and most of them are ornamented in some way. In fact, entirely smooth spores may not even exist. Spores can be dark-colored or light-colored, spiny, warted, and even finely warted. They come in different shapes and sizes. Spores vary so greatly that some of them can only be identified by the outer casing.
What is the most common type of plasmodium?
There are four different types of plasmodium. The most common type is the phaneroplasmodium, which has a fan-shaped network of veins that actually contain protoplasm. Then, there’s aphanoplasmodium, which has very thin veins and no slime sheathe. Protoplasmodium is the third type and it has no veins. These are always microscopic with a fruiting body. The final type of myxomycete actually has characteristics of both aphanoplasmodia and phaneroplasmodia.

Myxomycetes, also called Mycetozoa, phylum of funguslike organisms within the kingdom Protista, commonly known as true slime molds.

Where are spores borne?
This gives rise to fruiting structures (sporangia) with one to many spores at the head of a stalk. In nearly all species, spores are borne within the sporangium. In Ceratiomyxa, spores are apparently borne externally; each, however, may be a much-reduced sporangium with a true spore within.
Is plasmodium a sexual organism?
Formerly, it was believed that reproduction involved the nonsexual fusion of swarm cells, but the process is now thought to be sexual. The plasmodium, with cytoplasm streaming through it, changes shape as it crawls over or within damp wood, leaves, or soil, ingesting bacteria, molds, and fungi.

What are the chemicals that fungi produce?
Stachybotrys and some other fungi may produce several toxic chemicals called mycotoxins. Mycotoxins can be present in spores and small mold fragments released into the air. Once the mold fragments, mycotoxins and spores are in the air, individuals may breathe them into their lungs.
