possibly slime mold feeding on bracket

Description:

Slime molds begin life as amoeba-like cells. These unicellular amoebae are commonly haploid and multiply if they encounter their favorite food, bacteria. These amoebae can mate if they encounter the correct mating type and form zygotes which then grow into plasmodia. These contain many nuclei without cell membranes between them, which can grow to be meters in size. One variety is often seen as a slimy yellow network in and on rotting logs. The amoebae and the plasmodia engulf microorganisms. The plasmodium grows into an interconnected network of protoplasmic strands. ------Within each protoplasmic strand the cytoplasmic contents rapidly stream. If one strand is carefully watched for about 50 seconds the cytoplasm can be seen to slow, stop, and then reverse direction. The streaming protoplasm within a plasmodial strand can reach speeds of up to 1.35 mm per second which is the fastest rate recorded for any micro-organism. Migration of the plasmodium is accomplished when more protoplasm streams to advancing areas and protoplasm is withdrawn from rear areas. When the food supply wanes, the plasmodium will migrate to the surface of its substrate and transform into rigid fruiting bodies. The fruiting bodies or sporangia are what we commonly see; they superficially look like fungi or molds but are not related to the true fungi. These sporangia will then release spores which hatch into amoebae to begin the life cycle again

Habitat:

A plasmodium is an amoeboid, multinucleate and naked mass of protoplasm having many diploid nuclei and is the result of many nuclear divisions without cytokinesis (coenocyte) and it usually refers to the feeding stage of macroscopic slime molds (i.e. myxomycetes). It can also refer to the multinucleate developmental stages (i.e merogonial plasmodium and sporogonial plasmodium) of intracellular parasitic cnidosporans (Microsporidia and Myxosporidia).

Notes:

i'm not sure about, first the bracket cought my attention. But standing before it, i noticed: it was covered with those red stuff (slime, jelly,plastic-look). I recently posted this ( http://www.projectnoah.org/spottings/845... ) spotting, those 2 combined let me assume: i have here a feeding :" Dictydiaethalium plumbeum ", but it is to unsure for a species id. Because the bracket is covered in that red stuff, and this is a unusual sight or me, i think it is at least a predator- mold , it has no fluffy/hairy surface ( fungi-mold), therefore i do, tend to say : it could be a slime mold (amoebozoa)

thanks clive,we all learn through mistakes, i have made something out of the id , which goes the middle-way ! Like to hear always your honest opinion,when you notice something at my spottings.:)

i know, that was why i hesitated to post it, but after days of reminding me at this ( http://www.projectnoah.org/spottings/845... ) spotting, i thought it was going in the right direction. Without the pink (but the other spotting looked also more red to me), and the surface (back then , i hadn't thought of slime mold and thought: weird bracket).I have cropped one picture, what do you think, and if: not !- Is there the possibility, that it is at least slime mold? otherwise i take it out.

what do you think about this id, whats your opinion??? i like to hear !! as mentioned, i'm also not sure, but thats what i come up with, the red seems not to belong to the bracket.
