What kind of time frame are we talking about? Are these blooming size
tubers that have been put back on a yearly cycle for any length of time,
but still stored overwinter out of ground (say, in a crisper)?"

I regularly stored A. triphyllum tubers in a cool room in a paper bag for
well over a decade with great results. Never lost one or had one refuse to
perform well in the spring when they were started indoors a few weeks early.

What species were affected? How did they croak: Just rot away?

This may bode ill ... <8-O
