Family Ceratiomyxaceae.
This is a common and widespread plasmodial slime mould known as Coral slime.
They are found on decaying wood.
The plasmodium is thin, usually translucent or white and is covered in mucous.
Fruiting bodies are white or translucent finger-like columns around 2 mm high.
Sometimes the columns branch.
There may be single columns but they often form colonies up to a metre or more in size.
White spores developing on the sides of the columns are attached by a slender thread-like stalk.
