Thanking SARCODON, now I know what the subject is:

IT is Leocarpus fragilis (Dickson 1785) Rostafinski 1874. It belongs to the Myxomycetes CLASS and for the modern systematic it isn't a fungus.

As for ptotoctista.

Members of this class are commonly referred to as slime moulds. These have thought to belong to both animal and fungi kingdoms at one time or another. It's now known that they are quite unrelated to animals and fungi and now are classified in the Kingdom Protista.

However slime moulds do exhibit characteristics of both fungi and animals. In the feeding stage, the slime moulds moves about as a mass of protoplasm (the plasmodium) feeding on bacteria, spores, and other organic matter much like an amoeba. When the food supply is exhausted or other unfavourable conditions occur, the plasmodium changes, taking on the appearance of a fungus

Types
There are two main groups of slime moulds in the Protista Kingdom.

1 - Plasmodial slime moulds or true slime moulds are a large single-celled mass with thousands of nuclei called a plasmodium. They are formed when individual flagellated cells swarm together and fuse. The result is one large bag of cytoplasm with many diploid nuclei.

2 - Cellular slime moulds spend most of their lives as separate single-celled amoeboid protists, but upon the release of a chemical signal, the individual cells aggregate into a great swarm, known as a pseudoplasmodia and eventually muticellular slugs.

P.S. I went to forest to hunt mushrooms and there was no sun and it was raining all the time... So these bright little bubbles were a colourful spot in the Autumn forest and drew my attention. Though there was not so much light and i had no tripod with me. So as a result - not very good Depth of Focus with 2.2 F-point.

Very good close up, you had a small DOF but made good use of it. Clear and detailed.
Very interesting subject, and great info about it. Again added to my theme :)
About your "calocera cornea" it is not a slime mould o Protoctista, but a fungus. Regards, Felipe.
PD: This would be great with F8 and tripod ;)

Wonderful photo showing some developing Leocarpus fragilis the will go brown as they mature.
