Ceratiomyxa fruticulosa

Ceratiomyxa fruticulosa (IJsvingertjes (BE) / Coral slime (EN) / Kleinstrauchiger Wachsschleimpilz (DE) / buisson cireux (FR) ) is a slime mold. While not fungi, slime molds often form spore-bearing structures that resemble those of the true fungi. Although many slime mold species fruit on wood they do not form a penetrating and absorptive mass of hyphae in the wood substrate. Rather, slime molds form structures called plasmodia which are naked (i.e., without cell walls) masses of protoplasm which can move and engulf particles of food in an amoeboid manner. Slime mold plasmodia creep about over the surfaces of materials, engulfing bacteria, spores of fungi and plants, protozoa, and particles of nonliving organic matter. At some point, plasmodia convert into spore-bearing structures. In Ceratiomyxa fruticulosa, the plasmodium converts into a clustered mass of stalks bearing spores on their surfaces. There is evidence that the spores are actually one-celled sporangia. Individual fruit bodies are 0.5-1 mm wide and 1-5 mm high. Great numbers can occur on a log or piece of wood covering many centimeters or even a meter or more of woody surface.

I find the presence of the leaf excellent in the composition

@Veronique: After making some images with the leave as it was naturally placed there, I removed the leave to make some more images, but I preferred the ones with the leave too. I think it ads a little dimention-reference an surely some more color to the image. Glad you like it too. Nice weekend, Veronique !

Nice composition with the leaf in the frame. That is really interesting information. So, slime molds do not look slimy?

@Julie Brown: The "plasmodium" can be very, very slimy (can be seen in the image - the light-reflecting parts on the trunk) where the actual fruiting body is moslty rather dry. But off course there is a huge difference between the different species. These slime molds are just so weard organisms ...

Good combination and composition!

@Marilla: Thank you, Marilla. Are there some slime molds in Finland ? I suppose so, but don't know how they look like.
