🔹Los mixomicetos son un grupo de protistas denominados como mohos mucilaginosos, se clasifican junto con las amebas y comprenden unas 1200 especies conocidas. Son organismos microscópicos, heterótrofos, fagotróficos, no patógenos, que contribuyen a descomponer los restos vegetales. Se pueden encontrar tanto en forma unicelular como agrupados.
Se alimentan de bacterias, materia orgánica, esporas de otros hongos, levaduras, hojarasca, ramillas en descomposición o la misma hierba de un prado.
🔹Mixomycetes are a group of protists known as mucilaginous moulds, are classified together with amoebas and comprise about 1200 known species. They are microscopic, heterotrophic, phagotrophic, non-pathogenic organisms that contribute to the decomposition of plant remains. They can be found in unicellular form as well as grouped.
They feed on bacteria, organic matter, spores from other fungi, yeasts, leaves, decomposing twigs or the same grass as a meadow.

I am reposting this glorious #SlimeMold#Plasmodium video from a few weeks ago because I went back a day later and got pictures of the fruiting body since slime molds are not identifiable without them. Those pics are at the end of the video. And if you swipe after the video, I also included still photographs if you want a closer look. The video shows the rotting #Maitake where the slime mold started, then the #foraging plasmodium, then a picture of the tree the next day after the plasmodium retreated, and finally pictures of the fruiting body, which turned out to be #PhysarumPolycephalus , the many-headed #Physarum , I guess, which focuses on fungi as a substrate. Enjoy!! #Myxomycetes#Myxo#Myxophilia#Haddonfield#CrowsWoods#NatureStudy
The other day I found an exceptionally long and lanky species of Stemonitis, also called the chocolate tube slime mold. Stemonitis slime molds are not fungi, but ameboid protists called myxomycetes (myxo- is Latin for mucus or slime and -mycete is Latin for fungi). These live as haploid, independent single cells engulfing bacteria, spores and other microscopic sources of food. When two haploid cells of the right mating type meet, they fuse iand grow into a diploid plasmodium, literally a gigantic single cell with thousands of nuclei which can easily be seen with the naked eye. This plasmodium can move across the ground, leaves, etc to a location the slime mold deems appropriate and then forms sporulating structures like the chocolate tubes you see here. The spores are cast off into the wind in hopes of landing on a damp, rotting log to start the cycle over again. #slimemold#slimemolds#myxomycetes#myxomycota#fungifreaks#shroomatnoon#forestfloor#nature#protist#stemonitis#stemonitidaceae#chocolatetubeslime#chocolatetubeslimemold#forest#leaflitter#rottenlog
Fuligo sp; possible Fuligo septica (Dog vomit slime mold)
Yes I know, that common name isn’t a pleasant one. But trust me, there are far worst common names out there.
At first glance, this may look like just another patch of moss. I also thought it was so. That’s understandable considering that this aethalial sporophore seemed to have been out for quite a while. In my case, it’s almost impossible to determine how old this one was. So I’m taking a shot in the dark and guessing it was possibly as old as a few weeks based on how dry yet intact the structure was. It wasn’t until I touched it and realized it was actually a slime mold aethalium! You can easily see where my finger was. An aethalium is another type of slime mold spore-bearing body or sporophore. I had to bump the saturation in the photo to show that you can also see the plasmodial remnants around the aethalium. Those are the grey-blue amoeboid shapes surrounding the aethalium. What that means is that while it was still in its plasmodial stage, the slime mold made its way out of the oak substrate to only realize it couldn’t sustain itself at this location. So in response, the organism converted itself into the sporophore. Hopefully, those spores made their way to a better environment to take refuge.
Не грибы и не животные. Точнее, вообще не опистоконты. Слизевики, царство Амёбозои:
1. Trichia decipiens
2. Amaurochaete atra
3. Lycogala epidendrum
4. Brefeldia maxima
5. Fuligo septica
Cribraria sp. (Cribraria; No common name)
Just another member of the Trichiaceae family from my mycology lab. This is another reason I am so fascinated with myxomycetes! Their sporangia can come in a multitude of colors! All that raspberry sorbet-colored puff that’s coming out of the sporangia? That’s the mass containing the capitula and spores that will eventually be spread via a multitude of vectors. The most common is via wind dispersal. However it is not uncommon for animal dispersal to occur as well. My professor had a picture in lecture of a Rough-skinned newt (Taricha granulosa) covered in spores! Luckily the spores would have had no effect on the newt as they are not designed to parasitize any animal.
Rakkaita eliölajeja: kartiosudenmaito (Lycogala conicum). Ne ovat nuo pienet punaiset; suuret ruskeat ovat tavallista sudenmaitoa. Voin ylpeänä kertoa, että löysin tuon harvinaisen limasienilajin vuonna 2017 ensimmäisenä Suomesta! #limasieni#hankasalmi#slimemold#myxomycetes#lycogala
