Since you are the one who knows what the bulb looked like, can you describe it a bit better?
I would hate to suggest digging it up.
I used Google Images and looked for a plant bulb identification aid such as this one:

You could look at other charts of different bulbs and tell us what the bulb looked like by comparing it to the charts.
Not every bulb is listed on the charts but they might serve to help us to 'see' the bulb.
