Maybe it is G. vulcanalis but I was not convinced earlier for reasons below

G. vulcanalis is the closet I was able to come but I had rejected that name because the spores seeemed a bit short (7-9 microns) versus 8-11 microns for G. vulcanalis and the spores were not narrowed on the ends. Also the G. vulcanalis I have found in the past had a sulfur odor and this material did not. Finally, the margin of the cup did not look typical for G. vulcanalis. However, it could be that this material was older than what I have looked at previously.
Does anyone have other ideas or have experience with multiple collectionsof G. vulcanalis that had no odor even when crushed?.
