Probably it's due to mounting errors.  Send the slide to a
more experienced and capable stereo slide mounter, and then
it will probably fuse fine.  ;-)  <1>

Seems to me you've changed the question on us.  Originally
you wanted to know how the mushroom image could be made with-
out excess deviation.  Now you want to know why an image you
took seems hard to fuse.  But you haven't told us anything at
all about the deviation you recorded in your image.  Wouldn't
the first step be to measure the deviation in your image, and
then determine whether it falls within the guidelines?  If it
falls far outside the recommended max, then the fault is that
the stereo base was too large.  Next I would measure the infinity
point separation as mounted.  Maybe in an attempt to set a nice
stereo window the infinity point separation was made too large.
If that is not the problem, then I would consider compositional
issues such as those brought up by John Rupkalvis.

BTW, how about posting a scan so we can discuss it less
hypothetically?

for his mounting expertise!
