It would not appear to be virused, but it is infected w/ stagnospora, which
is present at various degrees of infection on about every hippeastrum I have
seen.  It is inherent in amaryllids, even in the wild!

There seems to be another related problem that can be seen at the neck -
this is some sort of rot.  When I get what looks similar to this it is
usually the result of a fly (which nobody's has been able to ID it) laying
eggs and they pupate at the soil level (the neck of the bulb) in the winter
and by the time you see the damage it is already in peril.  Several steps
can be taken to recover the bulb... the most drastic being cutting the top
half of the bulb off (until there is no more dark, necrotic tissue in the
center) and longitudunally quarter the remainder and place in peat.

Hippeastrums are lovely when in flower but can get to be dirty little
