Tiny white blobs on bare wood

Please try to include photos to show all parts of the fungus, eg top, stem, and gills.
Note any smells, and associated trees or plants (eg oak, birch). A spore print can be very useful.

Tiny white blobs on bare wood

Is this a fungus?
In the woods this has the form of tiny knobbly white spots about 0.3-0.5 mm diameter on bare wood. I thought it resembled Bactridium flavum. On examination it is made up of these elongated structures arising more or less from a point, each with an even covering of smooth lumps. There are tiny spherical bodies floating about in the water surrounding the warty finger-like structures which I take to be spores.
Can you tell me if this is a fungus or if not, what it is.

Hi,

it looks like Ceratiomyxa fruticulosa - a myxomycete. The globose spores are borne on stalks along the "fingers".

Thank you Dave but can it really be that? It seemed so much too definite in structure and although not measured the 'spores' seemed tiny. I must say I have never examined Ceratiomyxa fructulosa but always done the id in the field.
