Major problem!

The bulbs (Hymenocallis littoralis and harrisiana) I received not too long ago seemed okay when I got them. I planted them a day later (H. h in full ground and H. l in pots with potting soil) with hopes of growth the coming weeks.
However, something told me to dug 'm up to have a look at how they're doing, so I did. Turns out ALL my H. harrisiana bulbs are showing small fungal dots on the basal plate and one H. littoralis also. The old roots are soft, but the bulbs still feel firm.

What do I do? I've gone through so much trouble to get them. I don't want to loose them

Do you think the pots were too wet? Not having any experience with your type of bulb, I wonder if the 10% chlorine bleach solution - 1 part bleach to 10 parts water - (like what is done when storing dahlia tubers) would work to kill off the fungus.
