Who: Jessica Murray (jessica_gail)

Specimen available

Based on photographic comparisons, my specimen closely resembles Isaria tenuipes (aka I. japonica, aka Cordyceps takaomontana anamorph). I am not an entomologist so the closest I can come to identifying the pupa is recognizing it as a lepidoptera. An entomologist colleague guessed from a photo that it is a Hepialus humuli pupa, though the associate fungal parasite (Ophiocordyceps sinensis) does not match the description of my specimen.

The only geographical reports I have found of I. japonica are in Asia or Central America. I found this specimen in the foothills of the Southern Appalachian mountains.

host, and spore shape are all a match for I. tenuipes. good work, Jessica.
