preserved for study.

I think they are the same. I made a recent comment (another obs) about the split bulb being a defining macro-character for A. brunnescens. Perhaps this was an overstatement of the importance of this trait.

Great observation

Would love to know whether there are genetic differences between the two (split-bulb vs non-split) great enough to consider two separate species or variants.
