Pluteus pouzerianus doesn’t occur in the US or at least has not been confirmed from the US and there 6 other brown Pluteus species (only 3 on the West Coast) here that have clamp connections in the pileipellis and grow on conifer wood, so I changed the observations from the US to something more accurate. Adolf got upset about me changing the consensus by voting on IDs so he downvoted all of my proposals to keep the (incorrect) original IDs.

Pluteus findings?

Love the photomicrograph!

Fully understands that one should link mushroomobserver records with physical collections by using the observation number, not the consensus name.

I really doubt those features are a mistake.

I also doubt that Alan cares about me pointing him in the direction of a more accurate ID. Not correcting incorrect IDs leads to incorrect range maps as well.

Please, heelsplitter, stay away from changing the other users’names.

Deprecation and Consensus are features that are in MO by mistake. IF you have other “names”, post them in Comments and stay away from the other users’ observation names. Don’t change MO into a Ludo game.

Why downvote everything other than P. pouzarianus here? What does that accomplish? There are no confirmed finds of P. pouzarianus from North America and the other options I suggested are much more likely.
