Comment(by rgrout):

 well...maybe something could be done about making it more intuitive to
 find that part of the documentation.  I became so frustrated with this
 function that I ended up spending time and resources writing my own pdf
 function.  The docstring for scipy.stats.lognorm.pdf mentions nothing
 about the scale needing to be exp(mean).  Much wasted time and frustration
 could have been avoided had there been some sort of mention of this in the
 pdf docstring.
