I am requesting the addition of an additional official taxonomic rank in the ICN (“series,” https://www.iapt-taxon.org/nomen/pages/main/art_4.html?zoom_highlight=series ) be added to iNaturalist’s taxonomic hierarchy. This will add a finer level of sorting of species, especially in very large genera.…

There’s definitely a cost benefit to adding these additional ranks. Benefits being that they can help make groups more tractable and precise. Costs being that they add a lot of complexity to the tree and the rank menus. I don’t think we’re to a point where the size of any of the subsection groups on…

This solution presupposes that the other, already implemented ranks are in use in this genus; they largely are not. For some reason, people have skipped over the rank of subsection and preferred Series and “stirpes” in Amanita. The same is true in Orbilia, where the latest monograph separates the ge…

Then my preference would be to reappropriate existing ranks like complex or subsection for the purpose of series. I realize that theres a cost of misappropriating a familiar grouping as 'Series Soandso" as “Subsection Soandso” but IMO that is less than the cost of having such a complex list of ranks…

Okay. That is fine by me. I have been avoiding doing things like that because it is “technically” incorrect.

The use of subsections on that copied list of Amanita above are relatively new. I added the subsections of Gemmatae & Pantherinae to my observations to help build the tree. I started growing the tree with section Amanita because that is the only section that uses subsections to my knowledge. There…

Hi folks, Can we add the taxonomic rank of ‘Series’ as a necessary classification to properly organize species within Genus Amanita? I have some added free time being the offseason to address issues regarding the taxonomic hierarchy in Genus Amanita. I have begun documenting my 2020 collection be…

I will use my observation linked here as an example: Section Vaginatae (Amanita Sect. Vaginatae) from Glocester, RI, USA on September 08, 2020 at 11:59 AM by Spike. Amanita albemarlensis · iNaturalist

so, Section Vaginatae has over 400 described species under it’s umbrella. Within Section Vaginatae we have 6 ‘Series’ and 12 ‘Stirps’ (we do not use ‘Subsection’ in this ‘Section’). Of those 6 ‘Series’, they are also broken down into ‘Stirps’ Involving my linked observation above, ‘Series Penetra…

A note: this system has been in place for over 50 years: Persoonia v05n4.pdf (mykoweb.com)

I want to revive this thread, because we REALLY do need the taxonomic rank of series added as an option. According to Art 4.1 of the International Code of Nomenclature for algae, fungi, and plants, this is an officially accepted rank and anyone knowledgeable about fungi will tell you that we frequen…

Implement the botanical rank "series" between subsection and complex

If the zoologists can have included ranks like epifamily, parvorder and subterclass then I feel there is also room for the botanical series.

iNat ranks seem a bit zoo-biased.
