Jim McK,

I think Stagnospora is ubiquitous, and mechanical damage offers an easy 
route into the plants.  It attacks almost every amaryllid genus I've grown, 
including Clivia, Crinum, and Hymenocallis.  We had a very rainy summer and 
fall this year, and there was a lot of what looked to be Stagnospora 
around.  I didn't bother to stick any of it under a microscope, 
however.  Maybe I'll do that someday.
