Underwater was the cause then.
I have to water mine everyday during the summer. Drying them is really bad for them!

Any of you hippie experts know what it is?
My leaves are very floppy, but I can't do anything about the lack of sunny days, and it is way too tall to go under the orchid lights.

As Beverly points out, it is called Red Blotch disease and it is the most common fungal disease that attack amaryllis. It can show up as small red spots on the leaves, but when the infection is severe, it shows up everywhere, inside bulbs, on the surface of the bulbs, scapes...and the red blotch gets larger and larger to a point where affected plant part gets holes here and there, and sometimes these holes merge making a long slit and collapse. and as you mentioned, they get this dried up look too!
I read copper based spray helps, and also read hot water treatment, but I doubt its effectiveness. I haven't tried.
The best thing is to buy healthy bulbs, of course.
Oh, another thing, this particular disease hit field grown amayllis in the fall and any time of the year for the ones grown in the greenhouse.
High humidity and lower temperature combined with lower light contribute to the occurance of this disease.
so keep them leaves dry, give strong light and warmth while growing.
I do not buy amaryllis from big box stores, most I've seen (almost all!) that are sold as growing kit that come in paper box are badly infected, although there are exceptions. Even if I see just a few dark red specks on leaves or scapes, I stay away away. come home and wash my hands like crazy with soap.
Lucky, mine are all disease free, but I had some bad experience with one online vendor in Arizona. Every single bulb I ordered (and I ordered quite a few!) were infected, dried up, small, and just looked terrible.
I contacted them, they didn't care saying all bulbs have disease. I just threw them away and never deal with those people. They sell on their website and on eBay.
How ignorant or if they are intentionally selling sick bulbs to make some money to unsuspecting people, how sick!
They changed their ID name on ebay and for location is just says United States instead of Thatcher, Arizona (wow I still remember that name of the city!)
But their online store name hasn't changed and is still posted on their ebay listings.
My local farmers market flower guy carries healthy amaryllis, so I'm happy! I've bought quite a few from him every year and never had any problem. He buys from Dutch growers (where the best quality bulbs come from).
Many amaryllis sold around December in flower district here in New York also are infected. some look really bad even a blind person can tell!
