Keep finding this mushroom since the fall of 2009 at this location and two or three others. In 2012 the fungus has been described as new. I still can’t find any photos of it on the net so I provide some here sharing this beautiful tricky species. But keep in mind it is not sure yet if the ID is right.

I can’t post the sequence here for I do not know it … it is not yet published (was a part of the ongoing ABOL project (“Austrian Barcoding of Life”) which is not public but will be in the future as far as I know. As for the species you proposed odor is clearly different and some other features do not match.
I have found Musumecia several times over the course of the last eight years and there are some other photos from my findings floating around on MO here but if I could find them … I do not know the original label of my finds .. how to find them to put the names straight?

Exciting observation! Can you post the sequence here?

The photos are not a great match for the ones in the paper (, especially with the distinctive cap texture of your collection. However, Pogonoloma is in the same clade (along with Pseudoclitocybe and maybe Aspropaxillus), and photos online have a better cap texture match.
