I do love a mystery.
I could not find an exact match. The taro I am familiar with has more pronounced circular belts around it and it has more coarse hairs coming out.
@mudbug's photos strike me as sweet potatoes, of which I am so proud we grow so many of here in my home state. Come to find out in my research, that the whole USA produces only 1 million tonnes of the world crop, with China producing a completely overwhelming 81.7 million tonnes! Knowledge is always good, but sometimes very humbling, which is also probably good once one adjusts.
Sweet potatoes come in many skin and flesh colors, which may or may not match in the same tuber.
Here's a link to one that has a picture that looks maybe like mudbug's images except, the one in the link is fresher and not as dried out. Here's another link from the same site with an image of a baked white sweet potato where the author says something about this variety being more perishable than other sweet potatoes.
I will be interested to see if a definitive answer is ever arrived at.
