How can scientists classify deep sea mushrooms?

If theres mushrooms deep in the sea duh

Explanation:

mushroom-shaped organism is so mysterious that it seems to defy just about everything we know about animals. It doesn’t fit into any of the known categories in the animal kingdom, scientists say, and as of now, its links to other animal groups remain hazy.

A mushroom-shaped sea animal discovered off the Australian coast has defied classification in the tree of life.   A team of scientists at the University of Copenhagen says the tiny organism does not fit into any of the known subdivisions of the animal kingdom.   Such a situation has occurred only a handful of times in the last 100 years.  The organisms, which were originally collected in 1986, are described in the academic journal Plos One.   The authors of the article note several similarities with the bizarre and enigmatic soft-bodied life forms that lived between 635 and 540 million years ago - the span of Earth history known as the Ediacaran Period.   These organisms, too, have proven difficult to categorise and some researchers have even suggested they were failed experiments in multi-cellular life.   The authors of the paper recognise two new species of mushroom-shaped animal: Dendrogramma enigmatica and Dendrogramma discoides. Measuring only a few millimetres in size, the animals consist of a flattened disc and a stalk with a mouth on the end.
