I would like to, very much.

Yes, of course I know that.

But I often find all stages at once.

They are not formed yet

“During the plasmodial stage, individuals are reddish in color, but these are almost never seen. When conditions change, the individuals aggregate by means of chemical signaling to form an aethalium, or fruiting body. These appear as small cushion-like blobs measuring about 3–15 millimetres (0.12–0.59 in) in diameter. Colour is quite variable, ranging from pinkish-grey to yellowish-brown or greenish-black, with mature individuals tending towards the darker end. They may be either round or somewhat compressed with a warted or rough texture. While immature they are filled with a pink, paste-like fluid. With maturity the fluid becomes a powdery mass of minute gray spores. The spores measure 6 to 7.5 µm and are round in shape with a netted texture and appearing ochre to lavender in colour. The pseudocapillitia, sterile elements in the spore mass, are long, flattened, branching tubes with transverse wrinkles and folds.1


Could be.

I only miss the brownish ball-like structures that are usually accompanied.

For now

I’m convinced that this is a plasmodium stage of Lycogala epidendrum.

Or it is some myxo?

I am really puzzled hearing about “white hairs” and the last pic really looks like a cup fungus.
Concerning Fusarium and the like, don’t even try to search for a key, there are 1000 of anamorphs and all need heavy microscopy (minimal differences) and/or culture to make.
The more I look at it the more mysterious it gets.

the two below are soft, the one in the middle dryed without opening, and has white “hairs”, and the two of the top are opened and hard. Don’t seems Nectria to me, I was looking for scuttellinias, and found this odd thing, would say a bit larger than scuttellinias, at least the top ones, besides, my cam can´t photograph Nectrias. They seem to be some sort of bubble that crashes at some stage. The last photos (except the last one) are from a sliver that I found. How can I search the net, keys?

didn’t see the comments below.
Well, I think it’s either Cytospora or Fusarium stages of some Valsa or other Pyrenomycete.

as I said

the three below are soft, but the top two are hard. Don’t seem coming from under bark. It is a rotten stump… pine perhaps or eventually oak.

Which substrate?

What about consistency? Hard? Pliable? Soft, spongy, cheesy, like caviar?
Seems to be very tiny. Either something nectrioid or some anamorph like Cytospora?

I have the idea that

that little thing on the middle of the others (first photo) at a point “explode” and become like the top two. Inittially they are soft, and after “exploding” and drying they become hard.

something like Nectria
