Directly under hemlock, with birch and oak nearby. Not sure if this is a parasitized Geoglossum or an asexual Xylaria, which would be weird for this time of year. I dug as far down into the matrix of hemlock roots and got as far as I could before it snapped to retrieve yellow basal mycelium.

not sure if there is anything telling in those micrographs. for sexual spores of the Tolypocladium we would want to see either long threads or the fragmented pieces of those threads (“part spores”), which these images don’t clearly show. try again?

I added some photos of the “conidiophores” or whatever the white structures were coming off from the fruiting body. Stained blue. My scope with a camera only goes to 40x though, so I’m not sure how helpful it is, but I appreciate your interest.

some T. ophioglossoides with some white stuff covering the fertile apices at two different forays recently, and in both cases it was just a case of piles of spores stuck to the surface, but this still looks distinct to me.

That’s an interesting idea, Danny, but from what I was reading, it seems specific to Geoglossum.

is H. papulosporae known to occur on Tolypocladium (=Elaphocordyceps) stromata?

No distinct smell,

it had a firm, rubbery sheen when fresh and poking out of the leaf litter, now that it is drying and in the fridge it seems to get firmer. I will look at the conidia? under the scope tomorrow and post a pic. If I have the time I will try to get it in culture.

Huh, cool!

Neat find! What was the texture like? Any smell?

Good suggestion

I thought about some kind of Cordyceps and thus why I tried to dig so deep, I just have never seen one like this but that would explain the yellow mycelium.

I’m not sure

about my suggested ID, and I imagine folks with far more experience will weigh in on this. Cool find!
