not that all of these are positively IDed, of course.

Is this really as cosmopolitan as L. birnbaumii? And what of D. persimilis, if not other Delicatula species listed in that almighty monograph (if any exist)?

Where can I order Antonín, Vladimír and Machiel E. Noordeloos. 2004. A Monograph Of The Genera Hemimycena, Delicatula, Fayodia, Gamundia, Myxomphalia, Resinomycena, Rickenella, and Xeromphalina, I need a copy.
I also checked and the species is reported from Pennsylvania PA. Thank you. I do have the entire set of swiss books and i love them. We need something like that for here. John

thank you!

what clear-cut characters, altho indeed I suppose there could be something else entirely in PA. But it’s nice to give us a productive line of inquiry, at any rate…

One character of Delicatula is veins instead of true gills. They usually don’t reach the (dentate) cap margin. Another character is the white veil that leaves thin fibrils on the cap and stem. I think it’s more obvious on younger or larger specimen. This picture is an extreme close-up of very small ones.

From me this is just a “could be”, but I’m pretty convinced about the genus.
D. integrella is a well known species in Europe, and hardly impossible to find in Pennsylvania. But you could have others, of course.

OK Irene, a new one on me.

For those who don’t have Darv’s library (ie. most of us), what macro features led you to this ID? Altho reading the collectors description i can see where the genus name comes from!
