that Geoglossum nigritum is one of the most common of the earthtounges in North America too (I call it umbratile).
7-septate spores gives a handful of possible species, so you also need to study the paraphyses.
Here’s a nice and simple key to Geoglossum (british, but should also work for USA):

You have probably looked here already:

These mushrooms were <1.5 cm in height and the spores were 7-septate
