The commonest -

of the genus is called "honey fungus" - because of the colour. It's also called "bootlace", because the filaments (hyphae) are black.
They grow on tree stumps and roots, and can cause a lot of damage to economic forestry operations.
It was claimed that a specimen in the USA was the world's largest living organism, covering a huge area of several square miles. However, this has been disputed, because it is not clear how good the evidence is that it is all just the one individual, and not a colony. You may know that the "toadstools" we see are just the fruiting bodies, it is the much less visible hyphae that are the main part of the fungus.
