The pinkish, subviscid piliepellis is more common a feature of Hypholoma, but less common with Agrocybe (A. erebia sometimes has some brick colours). The overall stature reminds me of Hypholoma, not so much Agrocybe.

Okay, the name “Psathyrella gracilis”

may not refer to a single species. And maybe it’s debatable if/when this name should be used. But there are manuals out there that use the name, and for those mushroom enthusiasts who rely mainly upon the use of manuals, using the name may at least point in the right direction. If so, someone who knows about the difficulties associated with using the name may provide further clarification. Then people stand to learn some things.

The thing about the pink staining is a good example.

Ironically, when I look at the cap in this obs, there seems to be a pink blotch in the middle of it.

Actually, from what little I know about the genus Psathyrella, it seems like there are a lot of species, and not a lot of understanding about how to apply species names. With a few notable exceptions, I generally don’t get much past “Psathyrella” when I propose a name for one of my own collections.

I dont think you quite understand…

The Psathyrella gracilis group is a mess. Much more then any other Psathyrella group I have tried working with, the keys in the Smith book for them are largely unsatisfying and I’m questionable that they are very useful. I have an example of something in the group in obs 64930 which I will post micro for when I have time. And lastly, I meant more the “i’d call it that” vote rather then your “could be” vote. :)

Also, that rogers mushroom pic shows the pinkish staining the true P. gracilis should have quite well.

Judging any mushroom ID by a photo…

may be called bold. But without such proposals, albeit often at a low level of confidence, there would be precious little discussion here at Mushroom Observer. Certainly, there are people out there who know a lot more than I do about mushrooms in the Psathyrella genus. My “could be” proposal is merely a recognition that some things about this obs seems to fit a description of P. gracilis, and that Patrick (the collector) may want to check it out.


When I posted the proposal earlier today, I had forgotten it was Phillips’ account that brought this name to my mind.

Is a mess, applying names without microwork is rather bold, applying names with microwork is probably still rather bold, not to mention this looks nothing like them…

I’d suggest maybe Agrocybe.

I agree …

I was going with the general shape, gills are too dark for Xerula

are too brown for white-spored Hymenopellis (=Xerula)
