Observation 27263: Elaphocordyceps longisegmentis (Ginns) G.H. Sung, J.M. Sung & Spatafora

When: 2009-10-23

Collection location: Luzerne Co., Pennsylvania, USA [Click for map]

Who: Dave in NE PA

No specimen available

Looks a bit like Microglossum rufum, but too dark. Also seems similar to Mitrala elegans. Terrestrial on wood border. I didn’t pick it, but the person who did showed me the spot soon after doing so, and it was basically bare ground; seemingly unlikely from a dead insect. So I don’t think “Cordyceps.”

and it seems that capitata and longisegmentis may differ mainly in microscopic traits (although the one pic in the posted link really looks just like this observation). These were found on the boundary of an oak dominated woods, with a pine here and there.

In the past I have found and IDed Cordyceps

capitata, which now appears to be put into this other genus. These small slender specimens are different in several respects… slender yellowish stalk, small dark caps. Just did some online checking and found…

Except for size and color

these do look like Cordyceps capitata, which is an infrequent late fruiter around here. Host buried underground (as in capatata) seems like a good possibility. I’ve saved the small fruit bodies, if anyone is interested.
