The streaming protoplasm within a plasmodial strand can reach speeds of up to 1.35 mm per second, which is the fastest rate recorded for any microorganism. In urban areas, they are found on mulch or in the leaf mold in rain gutters, and also grow in air conditioners, especially when the drain is blocked. Myxomycota slime mold fungus Trichia decipiens macro selective focus shallow DOF It was concluded that cell contact between the compatible mating types needs to occur before macrocysts can form.[15]. A scientific study demonstrated the compatibility of these eleven mating types of Dictyostelium discoideum by monitoring the formation of macrocysts. These are about 2-3 mm tall and less than 1 mm in diameter. These amoebae then join up into a tiny multicellular slug-like coordinated creature, which crawls to an open lit place and grows into a fruiting body. [2] Most slime molds are smaller than a few centimeters, but some species may reach sizes up to several square meters and masses up to 20 kilograms. Trichia sp.

Other Physarum polycephalum may contain different combinations of the matA, matB, and matC genes, allowing over 500 possible variations. The protosteloids have characters intermediate between the previous two groups, but they are much smaller, the fruiting bodies only forming one to a few spores. When this organism has entered the stage of reproduction, it releases an attractant, called acrasin. The mold first densely filled the space with plasmodia, and then thinned the network to focus on efficiently connected branches. [13] Each cell is created with a random combination of the genes that the slime mold contains within its genome. Let me know if this is not correct. [18][19], Slime mold Physarum polycephalum was also used by Andrew Adamatzky from the University of the West of England and his colleagues world-wide in experimental laboratory approximations of motorway networks of 14 geographical areas: Australia, Africa, Belgium, Brazil, Canada, China, Germany, Iberia, Italy, Malaysia, Mexico, the Netherlands, UK and US. If one strand is carefully watched for about 50 seconds, the cytoplasm can be seen to slow, stop, and then reverse direction. Mushrooms (slime mould Trichia decipiens ) on an old stump. Slime mold or slime mould is an informal name given to several kinds of unrelated eukaryotic organisms that can live freely as single cells, but can aggregate together to form multicellular reproductive structures. Tweet; Description: Mature fruiting stage (sporangia) of a slime mold. Slime mold species of the genus Tubifera. [16] John Tyler Bonner, a professor of ecology known for his studies of slime molds, argues that they are "no more than a bag of amoebae encased in a thin slime sheath, yet they manage to have various behaviors that are equal to those of animals who possess muscles and nerves with ganglia – that is, simple brains. Trichia varia a Slime Mould: I found this colony on the inner wood of a very rotten Silver Birch tree, They start off white and change to yellow. Today, slime molds have been divided among several supergroups, none of which is included in the kingdom Fungi. They live in similar habitats and feed on microorganisms. Some of the amoebae become spores to begin the next generation, but some of the amoebae sacrifice themselves to become a dead stalk, lifting the spores up into the air. This process results in the plasmodium advancing in fan-like fronts. These sporangia will then release spores which hatch into amoebae to begin the life cycle again. [11] Physarum polycephalum is one species that has three sex genes – matA, matB, and matC. Similar life style to dictyostelids, but they are grouped within the paraphyletic group referred as.
