When doing some more research on this I found this Facebook group:
Carolina Snake Fungal Disease Project
Interesting stuff. If you search for "Oscar" and "2016-0016" you'll find info about him. He's an eastern black rat snake that had a case of SFD bad enough earlier this year they were considering euthanizing him. I've attached a before/after picture from one of the group's photos.
Also noteworthy was a post on Sep 9 about a gravid eastern king snake with SFD that they collected. She laid eggs, which were incubated, and apparently the babies developed SFD both in the egg (these were stillborn with SFD lesions), or the lesions showed up shortly after pipping.
