These are likely not anomalus. Like you say, I think alboviolaceus is a better possibility.

The robust violaceus Corts seem like a really difficult group.

Thicker than 1/4" which is in the proper range for this species. Also note the bulbous to clavate base.

are a bit thin for alboviolaceus. Here’s another name to check.

Looks like this name applies to a variety of slender silvery-violet corts.
