Recognized by sight: I think that your ID suggestion is a good one Irene, but entoloma works better for me than leptonia, what with that peaked cap…

posting a new OB is fine

Hey Christian,

I sent you my email address through MO, but I think your reply got buried in a wave of spam. Posting a new observation and then linking the two together, as Douglas recommended, is probably better anyway, because that way we both get equal credit if it turns out to be something significant.

I’m going to go look through my recycle bin…

Christian – just create a new obs. of this one, and post your photos and drawings. Then in the comments refer back to this obs., and site Dan. You can re-use one or some of his photos again in your new obs. Then you don’t have to transfer any stuff over e-mail to work it out later.

You can take a look at obs. 12263 to see what I did with Bolbitius viscosus with material from Dan.

So curious

I’m looking forward to see pictures and drawings uploaded – I want to learn more about these species too. All in this group are rare, and very few pictures of them available.
Christian, what literature are you using?

When it comes to the question about Leptonia/Entoloma, my own first choice is Entoloma, but since you prefer to use Leptonia as a genus instead of a section within Entoloma here on MO, I also did that – just to please..

Examined the specimen today. I will recheck the results tomorrow, but it doesn’t match E. allochroum exactly.
The spores are at the small end of the range, and the cheilocystidia aren’t as ornamented.
Also, the pigmentation of the pileipellis appears only intracellular and not encrusting. This points to E. dichroum, but that species is apparently differently colored macroscopically.

Dan if you send me your e-mail I will send you photos and drawings.

I look forward to learning more about this little purple guy :)

Hey Christian,

It’s drying now. I’ll send it out to you in a few days.

If you can get an herbarium specimen of this, I’d be very interested in looking at it.

pink spores are what we’d expect in a member of the entolomatacea…

which includes both Entolomas and Leptonias, among other genera. Macroscopically at least, it looks like a good match for Irene’s choice of _____ allochroum.

The million dollar question is whether “we” are calling it Leptonia or Entoloma these days…and despite the fact that Index Fungorum sez Entoloma, even Index Fungorum can be wrong/behind the times.

What’s a taxonomically bent gal or guy gonna do??! The best that they can in these changing times. Just don’t get your heart too set or take it personally when the name that you select turns out to be yesterday’s news…it’s the very same mushroom, regardless.

Pink spores fits what I know about Entoloma … but also appears to be true of Leptonia. Another taxonomic difference of opinion between here & the Continent.

Thanks for the ID ladies!

But what is the correct taxonomic category? My first inclination was Tricholoma, but the link Irene provided seems a good match. I’ve never run across a mushroom like this before, so I picked it and brought it home. The gills are pink this morning.

It reminds of Leptonia tjallingiorum. I’m sure there are some look-alikes, but I don’t know what you might have there.
