Anaxyrus americanus American Toad
The genus Anaxyrus was split from Bufo by Frost et al in 2006. This split is particularly controversial among herpetologists, and many references still use the long-established Bufo.
Subspecies I've seen:

Eastern American Toad (Anaxyrus americanus americanus)
I was with a group of snake-obsessed folks when we came across this fairly generic toad, so I just got a voucher shot and moved on to avoid wasting everyone's time. Only later did I realize that I hadn't seen this particular subspecies before. If I had, I probably would have tried to get a better photo.
Anaxyrus americanus charlesmithi Dwarf American Toad

Dwarf American Toad (Anaxyrus americanus charlesmithi)
This zaftig little toad was hopping about in the leaf litter following an afternoon shower, not fifty yards from where Meriwether Lewis met his fate in 1809.
