More issues with these name changes

Other problems with these kind of Name changes:

  • Both Index Fungorum and MycoBank list Lenzites betulina/betulinus as current;
  • Another user can simply re-create Lenzites betulina/betulinus, which will not have any indication whether it’s the Preferred MO Name.

Moral: Please don’t edit Names — especially the Scientific Name field — until you’ve used MO for a long time (6 weeks is way too short) and unless you are 100% certain you know all the side-effects. Instead, add a Comment and/or type a note in the Notes on Taxonomy.

I would prefer to discuss big changes like this

This affects some 200+ observations. Are we certain that everyone who has ever proposed this name agrees and would willingly change their name to Lenzites betulina if they had the time? If so, then by all means let’s make this sweeping change. It will save us a lot of time. Way faster than proposing and voting on that many observations!

But please contact the admins first. I just want to make sure it is a group decision that everyone is on board with.

If there has already been a discussion on facebook or elsewhere, that would probably suffice. Just include that in your comment in the future, and I’ll let it go.
