Looks like the best match after all (among the known species). We have seen other kinds of mushrooms changing habitats between Europe and North America, and this might have found other bryophytes suitable there – or they could have become different species but kept similar micro structures. Take good care of the herbarium specimen for the future!
I did feel that I was choosing between nearly equally attractive alternatives using Mains’ key to N. American Geoglossum. Arora says that G. glutinosum is perhaps the most common in our area, but I settled on G. glabrum because these were not viscid at all.
Given your information, though, I am going to change my “confidence rating”.
Thanks for the overseas ecological perspective!
What you describe of the micro characters fits many of the black earthtongues (many of them have dark, 7-septate spores with variable length) and is not diagnostic for glabrum in particular. I doubt that it is, because it’s a peatland species that grows with Sphagnum and has a cylindrical, long and slender stem.
