Talk about the taste of Pu 'er tea.

Pu 'er loose tea is fat in appearance, brownish red in color, pig liver color or grayish white.

A good cup of Pu 'er tea will not taste musty or bitter. The newly-made Pu 'er has white hair and has not been aged, so it will have bitterness; Pu 'er tea is mild and non-irritating, so it tastes mellow.

It won't taste like seaweed water to fungus water as you said.
