to see the spores!
E. longisegmentis is ruled out then. Could be capitata after all, although the tapering ends of the spores, and its “head” with a broad margin around the stem isn’t typical.

vary but with the scale in the eyepiece and the scale on a slide I used for callibration, the spores I measured were typically 21.2 microns and some were smaller. Another one I measured was about 18 microns.

appear to be too small for E. longisegmentis.

There’s also

the smallish valliformis, and maybe still some other undescribed species.
You should check the lenght of the spores to start with.

Beautiful specimen

and no doubt Elaphocordyceps, but there are other options than capitata, and making an ID without microscopy… I wouldn’t.
