Observation 20988: Nolanea verna (S. Lundell) Kotl. & Pouzar
When: 2009-05-11
No herbarium specimen

Notes: Id’ed by others at the Societe of Geneva. I think that they had gone through the effort to id these in the past, and these are a common Nolanea in the spring in the area. They called these an Entoloma, around here it seems all the Entoloma sections are still sections, and not genera. Some of the people here are kinda old-school.

Got your point, Paul..

What I meant is that it only makes sense to divide a genus if you can sort out the new ones as monophyletic groups (supported by micro/macrocharacters that make them possible to ID). But nearly all Entoloma subgenera are polyphyletic as they are described today. It seems possible to extract Nolanea, but what happens to the rest then? For example, only parts of subgenus Leptonia and Entoloma are monophyletic. If they are to be treated equally, Entoloma ends up with a lot more new species than today’s amount of subgenera, and that wouldn’t be easier to handle.

Let’s also put all the chordates in one genus — they’re monophyletic too!

Isn’t the best approach to keep them all in one genus, if it’s monophyletic?

New school!

Reducing the genera of Leptonia and Nolanea to Entoloma is the new view. The publication is pending – however, we can then ask philosophical questions about generic delimitation, as well as scientific questions about the appropriate molecular methods to establish that phylogeny.
