Arcyria incarnata.

This is not a plant, not animal, nor a fungus, it is a slime mould and is the closest I have ever got with my Sony, this are so small, that when you look at them you only see little dots. The diameter of this spongy cylinders is about 1mm. and they are about 2 mm. tall.
Viewed in my screen, at 1280x1024 the last shot is x23 scale.

I took the first, the second the day after, and returned one week later for the close ups.
For the bottom shots I also used the Sony F-717 with the Sony VCL-M3358 Close but added a thick lens taken out of a budget chinese wide angle adapter to get closer. Although the sony has great magnification, not enough to get a detail of this without magnifier (as you can see in the top pair). With the magnifier, quite a lot aberration apears, but better details are seen.

I found them in an excavation of a new forestal path, they where 2 meters high in the soil wall. I entended my tripod to maximun length, and it was a hard work to adjust it to the right focus plane. Then used auto shutter. Working in this size it is a pain, focus is so critical, that when you think you have it, and prepare to take the shot, if you just change the weight of your body from one leg to another, affects the tripod and focus dissapears. You cant even breathe :)

Kingdom: Protozoa
Phylum: Myxomycota
Class: Myxomycetes
Order: Trichiales
Family: Arcyriaceae
Genus: Arcyria
species: incarnata

Esporangios gregarios rojos a color de rosa brillante y rojo ocre claro, cilindricos, de 0.5 a 2mm de altura, unidos en la base por un hipotalo.
Pie café-rojizo, mas o menos largo y brillante, tubular y rugoso longitudinalmente.
Peridio solo restos en la base como un caliculo y como un pequeño capuchón en el ápice del esporangio.
Capilicio abundante y permanente, elástico, los filamentos capiliciales están ornamentados con estructuras transversales a manera de medios anillos protuberantes ,al microscopio de barrido parecen escamas, o placas.
Esporas globosas, de color rojo en masa y hialinas bajo el microscopio, la pared de las esporas tiene unas cuantas verrugas esparcidas.
Esporas de 7 a 8 micras (-10) de diámetro.

I borrowed this info HERE where there is nice info about it, although in spanish.

Hope you like!

Hola Felipe Mateo and Cristina,
this is a fine collection of pictures to introduce this organism. Excellent close-ups, despite some optical disadvantages, of these small creatures.
Best wishes, Peter

wow, what an amazing collage! :-)
never seen such an interesting mould before.
you did an extraordinary job here to overcome the technical
difficulties and present us actually 4 perfect photos in one.
thanks for showing us the "small" world & take care, thorsten.

Fantastic, you've done it once again! Really fascinating and excellent exposures of these tiny dots. Also very interesting notes!
Thanks a lot, Ulla

HI Felipe,
Tha is truly an amazing collage. Your hard work and dedication paid off here. The exposures look great. You have captured the colors and intricate detail of these oh so tiny Slime Molds extremely well. I used to notice fungi in the woods, but did not really study them. Viewing your work, and now having a macro lens, I think I am going to start trying some of these shots. I'll just need you help on the ID's

Curioso y detallado "póster" informativo.
Saludos, JL

Hurrah, a slime mould - I thought so! And Greg's on holiday - he'll be sorry to miss them. He gave us some lessons on them last year.
EXCELLENT macros Felipe and Cristina - they have magnified so well. Your hard work and patience has certainly paid off. Thank you my friends,

Ciao Filipe

What an interesting post!!!
I belive i've never seen anythink like it even thouogh i graduated biology...i really have to look in my old books for something like this!
Great work for all 4 shots, very good POVs, light and colors. The details are also very nice and sharp.

Bravo and TFS

Good morning Felipe,
Very short on time this morning.
Nice presentation, thanks for posting.
Have a great week.

Hi Felipe,
Nice to see your slime mould postings. You have done well capturing these very small organisms, better then my 20D does that for sure.

Informativa y pedagógica, como muchas de tus entregas Felipe.
Una composición con imágenes que nos permite apreciar en detalle, algo que muchos de nosotros, simplemente pasaríamos por alto por su tamaño.
Merecedora de su publicación, definitivamente.
Saludos para ambos... Ricardo

PS. suerte que la F717 seguirá funcionando, aunque sea como muletto :)

Agradecido por tu comentario compañero y sobre todo por la explicación de hongo del tronco del petirrojo (Tremella foliacea). Claro que interesa aprender siempre es bueno.
Bonita colección de esporangios captados con gran nitedez y colorio. Y sobre todo por que unos aprenden de pajarios y otras yerbas y otros de flores, hongos......
Un saludo

Perfect mosaic picture. Very good, lights, colours, and it is very clear. Well done on a great job.

Impressive your new electronic miscroscope ;-) Seriously your system is great and the result is good and interesting for this tiny species.
Bravo Felipe and TFS.

Hi Felipe,
I must have missed this one :)
This is another excellent presentation of the ultra small..I especially appreciate the detail in the two bottom shots. They look like miniature brillo pads ;)
Very well done mf.

Fascinating post Felipe, I see you have adapted the measure for some of your posts which is good to emphasize the scale of these wonders. Very good images in each case. Informative note makes for a good read. Very good work from you, well done.

I have never seen such things beforem it is very interesting ! Each shot is of excellent quality, and could easilz stand alone. It is nice to see 4 different views on one single picture, and I like how you indicate the size on the photo. Both the picutre and the note are very instructive.

Wyśmienite makro Felipe. Też się w takie coś bawie i wiem jak trudno zrobić takie maleństwa. Perfekcyjna robota.
