White-flowered Erythronium americanum?

All the recent posts about white-flowered Erythronium dens-canis have got me
thinking about the local white-flowered Erythronium.

Can anyone tell me if Erythronium americanum has white-flowered forms?

I know of two local populations of E. americanum among which grow plants
with white flowers. The white-flowered plants produce flowers which are
comparatively wimpy and have distinctly bluish leaves. In the location I've
seen most often, the white-flowered plants are almost certainly a clone:
they grow in a big patch (of foliage, not flowers!) about a yard or two

It seems very unlikely to me that these are E. albidum, although everyone
I've ever asked uses that name for them. 

Any thoughts?

heavy rain last night made literally true the term "spring ephemerals".
