I say Much as in mushroom, and ae (long a) - suhs.  
However, I have only read about these - There is only one other person I know (at work) who even knows what in the world I would be talking about.  Thus, I am saying these words having only read them, never really heard them.
I like to call this the place-bo (like place and bow) effect.  As a child, I read a lot, and somewhere had rea about hte placebo effect.  However, I had never heard it used in speech.  So one day my aunt I were talking and I said "That's the place-bow effect".  She was a little confused by it until she realized what I was saying.  This is an effect common to people who read "too much", or try to learn words in languages they don't know. =)
