Howard McGee did an experiment to see if mushrooms would absorb water. The mushrooms didn't absorb water after being soaked for 5 minutes. However, these were white button mushrooms. McGee also noted that the flavor could possibly be affected by a loss of amino acids, although he was skeptical about a loss of flavor.
Here's a research paper on the effect of blanching chanterelles with regard to how well they can be restored after being dried:

Here (third down) is a lengthy discussion about the blanching technique, somewhat

In both, there is a lamentable and noticeable lack of discussion of ordure and grit.
