I think what you propose would be a relatively easy feature to add, if proposed either at the “Feature Tracker” here on the site (link to your left), or over at PivotalTracker. Sorting/displaying a species list by genera or family could be useful. However, in the meantime, duplicating your observation(s) to fit neatly into a genus-only species list seems like a needlessly messy and problematic way to achieve this.

Thanks, Dan

Thanks for your patience, Dan. I’m still not sure if constructing the NA macrolichen list in that manner is a good idea. On the one hand, I quite like the idea of having a list of all NA macrolichens in MO, but on the other hand, I keep bumping into my own “observations that are not observations.” Hmmm. Maybe there is a cleaner way to achieve the same goal. In any event, implementing the concept of a NA macrolichen list certainly did prove that there is a magnificent collection of macrolichen photos here on MO!

Makes sense

I gave Multiclavula an ’I’d call it that’, no votes for a species name yet. Hope it works.

To create a list of genera.

The goal was to create a list of the genera of NA macrolichens. One way to achieve that is to make a list of observations of genera, and use the “Show Names” switch to turn that into a list of pointers to generic name pages.

It seems that there are side effects to that approach, however. If an image is reused on such a page, it becomes exposed to votes on its identification, for instance, outside of the context of the original observation. I had not anticipated that.

Just to continue that thought, my purpose with this particular observation is just to use it as a standin, so that a pointer to the genus page for Multiclavula will be created when one clicks on “Show Names.”, But I happened to decorate it with this beautiful image. Now someone comes along, recognizes the image as Multiclavula mucida, and votes for that name with sufficient vigor to change the identification of the observation from Multiclavula to Multiclavula mucida. Well, that just broke the list of macrolichen genera. It is now a list of genera and one species.

A more robust way of creating lists of pointers might be useful. And care is certainly called for when reusing images on MO, especially someone else’s images.

Why make a duplicate observation?
