Kingdom: Protista
Division: Myxomycota (slime moulds)
Class: Myxomycetes (true slime moulds)
Subclass: Myxogastromycetidae
Orders: Stemonitales
Family: Stemonitaceae
Genus and species: Stemonitis axifera

Off all the species of Stemonitis, this is probably the most common, being found in all kinds of forests through out the world on slightly decayed but still solid wood. As with many members of this genus. the white or pale to bright yellow plasmodium is able to find its way through decaying wood. This enables fruitings to occur on relatively dry logs after the plasmodium emerges from within the log where conditions are still most.

The stalked reddish-brown to chocolate-brown fruiting bodies (sporangia) are found in small clusters that range from 10 to 50 mm in diameter, with a height of 7 to 15 mm. The individual sporangia are 0.2 to 0.3 in diameter. The stalk, which is black and shiny, extends into the spore mass as a central support column (columella) and a network (capillitium) provides support for the spore mass. The spores are light brown, 5 to 7 µm in diameter and almost smooth (minutely punctuate).

Hope you like!

Both are long exposure shots with natural light using with minitripod and manual exposure in ISO100.
Top: F:32 - 30 seconds.
Bottom: F:22 - 25 seconds.

Hi Felipe!

Another old but gold picture! Of course I like it. I've never seen this slime mould in real life, it looks great and it must be fascinating to see its all stages of life. As always very good post with clear and sharp pictures and interesting note. Not fungus but also great subject my friend :-)

Good morning Felipe..
I do bugs, you do fungi - Some things never change it seems :)
Great images all, done to your usual high standard of excellence. Perfect exposure and natural colors.
Very well done.
Howard

Hello Felipe,
You open up an aspect of nature that I, like the vast majority of people, know nothing about. Of course it is mainly because it is a microscopic world and your fine macro photo gives us an excellent insight. The use of long exposure in natural lighting is very succccssful to show two sharp, well composed and well coloured images of Stemonitis axifera.
Well done and TFS!
Ivan

Hello Felipe,

What a excellent photo you show us here . I have never see this fungi before. Thanks for showing me these little fellers. Wonderful. I "think" naturel colours. Just what ARGUS said: You gives us an excellent insight in the microscopic world with your fine macro photo's. Regards and TFS Bob

Hello Felipe and Cristina,

Many thanks, Ulla

Como se nota que vuelve la temporada. Me alegro compañy. excelente definicion

Hi Felipe & Cristina,
Very rare looking fungi. First I thought some type of termite house in wood. Very nicely taken with very good details and informative notes. Thanks a lot for sharing.

Hello Felipe,
I remember Clives wonderful post of this species. They are such strange looking things.
They look like they might be hard to shoot, perhaps because of the colour as well as the fact that they prefer darker places.
I'm looking forward to finding these one day.
A very interesting note about the species.
Great post.
Cheers,Steve

Hola Felipe,
¡Asombrasa geometría! Me ha desconcertado este honguito y lo voy a marcar!
Abrazo, José M.

Impresionante. El mundo de las setas es rarisimo (tambien)

Hola otra vez.
Esta foto la vio mi hijo y me dice que le parecía unas barras de chocolate.
Es de una calidad impresionante. La base de la planta me recuerda las suturas, ésas que "te cosen" en el hospital.
Un saludo y otra vez gracias, JL.

Hola Felipe y Cristina.

Que cosa tan rara, yo mismo fotografie una muy parecida que brotaba de un tronco pero con los filamentos mas finos como que parecia pelo grueso pero como tenia una vista algo borrosa no vale para enseñar.

Saludos a los dos.
Jose Luis.
