"Most of the Physarum I have obtained through moist chamber cultures have all been yellow in color, however, I read where the color can sometimes be due to the pH of the substrate on which the plasmodium resides. Again, however,…"
"Why are they adverse to light? Good question, I am not sure of that myself but reading your post had me looking at positive and negative phototaxis and how it plays out in prokaryotic and eukaryotic organisms. I did not quite find…"
The genus may be Badhamia sp. but I cannot be sure. Doing a little research, the plasmodium of both Badhamia and Physarum polycephalum can look pretty much the same. So, to an untrained eye, such as mine, they may be easily confused. Anyway this…
I oftentimes use my Axiostar much like a CMO dissecting microscope, the scale bar was made by photographing a plastic ruler at 100x, so I cannot attest to its accuracy, however a microscope stage micrometer is in my future. Corticolous myxomycetes…
Could be P. polycephalum, not sure. However there are quite a number of cellular (social amoebae) slime mold fruit bodies, appearing as bright specks of dust, associated with it. These are Dictyostelium.
The result of Physarum plasmodium in culture, image 0045 posted 4/26/20. Prior to fruiting the plasmodium grew substantially in size from approx .5 cm to a little over 1 cm.
Moist chamber culture 4/5/20. Substrate is bark pieces from Flowering dogwood tree. These cultures have been very fruitful when it comes to producing a plasmodium.
"I would venture a guess that human activity, insects, wind, and wildlife all play a role in the dispersal of slime molds. As for displacement of other organisms, I really haven't given much thought too but it could be possible I…"
What is your interest in slime moulds? (we need to know you're not a bot or spamster)
Citizen scientist, amateur naturalist and researcher who studies Eumycetozoans among others. Currently my studies are of corticolous myxomycetes, fungi and other tree bark-dwelling organisms. Other interests include Paleontology, Geology, Mass extinctions, Evolution and environmental science
