The spores

are too broad for capitata and too short for longisegmentis, but it has a shiny head and a palisade structure like longisegmentis.
There’s one delicatistipitata with the right size of spores, but that is a very slender mushroom (head ca 3 millimeters, and the stem less than one millimeter – and it doesn’t grow directly on the host..). This one’s bigger, isn’t it?

I think this is a variant of longisegmentis with shorter spores – or an undescribed species close to it.

Quote from http://cordyceps.us/... :

""the problems of C. capitata group are still not solved and although Ginns (1988) stated that “…in some C. capitata stromata most spore segments were 15–20, in others they were 20–27 and in still others 17–24. When a number of stromata are examined the segment length form an overlapping series and to me represent one species.” this may not be true. We have observed similar differences in C. longisegmentis, where the ascospore parts were from 26–35 μm to 41–83 μm long.""
