Sydney,

For Mycena, cheilocystidia and caulocystidia carry more valuable information than spore features. If we have time to prepare only one slide, then it’s the slice of the gill edge to put under the scope and see cheilocystidia.

I agree that your mushroom is most likely M. leptocephala. For positive determination, caulocystidia with their characteristic irregularly inflated shapes are the most useful. The odor is also important to check: “nitrous” for this Mycena.

I hope you don’t mind this advice. I’m just glad to see Mycena postings with microscopy.
