Missed the pitted rough stipe.

Most likely Mutinus.

My spore sizes are almost perfectly between both elegans and caninus according to the measurement provided by Kuo: “Spores 3.5-5 × 1.5-2 µ (Mutinus caninus and Mutinus ravenelii); 4-7 × 2-3 µ (Mutinus elegans)”
I can’t distinguish other factors that might help, but I’ll trust the other vote here and the narrowed tip and go with elegans.
Very unsatisfying microscopy!

Elegant

On second look and reading descriptions, the stem gradually narrowing to the tip and being wider in the middle (uneven) seems diagnostic for M. elegans. This specimen is just a shorter one and the slime area isn’t as long, I guess. I may still check spores later to confirm (luckily the size ranges don’t overlap, much).

Mycowalt – can you please explain why you propose elegans? The distinctions from Kuo seem like they would be variable, so maybe you are suggesting either one is about as likely. Perhaps I will need to measure spores.
