Can a giant mushroom be used as a material to build watercraft or sailing ships?

The basis for this question is the selected answer for Plausibility of Mushroom Buildings. Prototaxites and braket fungus are the likely candidates but I want to know if this type of fungis can float on water or not, so that it can be used to build a ship.

My question is not restricted to that fungus, it is just generally about the possibility to build ship with giant mushrooms. If simple giant mushrooms can do it and can be hard enough to withstand ocean waves, impacts and other nautical challenges in order to be viable as a ship then it's good enough.

Feel free to suggest new solutions or alternatives from any fungal or fungal-like organic material if prototaxites and braket fungus is not suitable to build ships with, as long its not the obvious trees and metals as materials.
