“Chocolate Tube Slime” (Stemonitis fusca)

…although it may look like a fungus S.fusca is actually a amoebozoan protist that is found worldwide. Like some other slime molds they typically grow in clusters on rotting wood and are characterized by their tall brown sporangia (spores) which are supported by slender stalks.

Myxomycete - Badhamia utricularis

A group of yellow sporangia of the cosmopolitan slime mold Badhamia utricularis with its pedicels attached, giving them the appearance of bunches of grapes hanging from the substrate (dead wood and bark).

When we found some fresh myxogastria (german: Schleimpilze) in one of our hermetospheres – our biologist friend “Dr. Bob” told us how fast they can grow and we shoud make some pictures as proof - so we did. The animation is made from pics of a periode of only 2 and a quater hours. The last pic we made the next morning: the plasmodium turned into fruit bodies
Specimen: C-13
Time of hermetical insularity: 1 month

Slime mold 

These are the fruiting bodies (sporocarps) of the slime mold identified as Arcyria cinerea (Trichiida - Arcyriaceae), a cosmopolitan and common species of myxomycete, that grows on dead wood, logs and branches, barks of living trees, or plant debris.

Although the usual color of this species is gray to light ochraceous buff, or olive buff, the coloration and shape is quite variable as these ones that are very dark.

Slime Molds: Our Beautiful Granddaddies

You can read all about slime mold yourself, but I’ll just show you its sexy bits: that it spreads the same way amoebas do, making it kind of animal-y (note that they’re right next to animals in the phylogenetic tree—-> Slime molds are our ancestors!!! 

Their cells also find each other when seperated, just like that golden retriever, and can predict poor conditions, leading some scientists to conclude that they have “simple brains”.

Which explains mine. Behold the beauty:

“Can you cultivate slime mold?" 

…Was the first question I asked in my biology lecture. The answer:
”……Well.     Are you asking if anyone does? Because nobody does.

But you could.“

But I could*~*~*~*!*!! 

Happy Wednesday.
