Notes:
Kathie T. Hodge co-authored the Eryniopsis paper mentioned above and ID’d both the insect and fungus. Thank you Kathie!
Eryniopsis caroliniana (Thaxter)Humber.
I found this insect about 8’ up a large dead birch tree in New Hampshire. It was easy to spot as it was attached to a large swath of a resupinate species of Phellinus which was a uniform rusty brown color. I was able to obtain the specimen and get it home to work up without smashing it.
The insect is a Tipula sp. and I think a female.
