Have you had a chance to look at this?

I will send you some of the dried material. This was tough and fleshy without any discernable smell. It was so firmly attached to the log that I wasn’t able to pry it off by hand and had to use a knife.

Well, that’s just odd. It COULD be a large, misshapen, immature Xylaria, certainly, but I can’t really tell from these photos. It could also be a mushroom, parasitized by some sort of Hyphomycete or the like, and misshapen because of the infection.

Was it hard and firm to the touch, or soft and squishy? Any scent?

A slide of the white powdery surface would tell you, I think — the conidiophores of the immature Xylaria are relatively distinctive (though you have to find the conidiophores amongst all the conidia to know). I’d take a look, if you wanted to send me some of the material you dried!

Definitely a weirdo.

This thing was growing from the bottom of the same hickory log as my observation 211856 from last summer. Unfortunately, I cut it from the log to better photograph it. I did dry a few pieces, if you’re interested.

Dumb question: Is Xylaria considered mature when the entire surface goes powdery?

strange

i hesitate to call this Xylaria without seeing it mature. revisit in a few days/week?
