I’m going to leave this post as is until I can post some better pics.

to photograph and post this collection. In fact, you may consider destroying this obs, as it is essentially the same as…

I photo graphed and posted this for you awhile back.

Thanks for the advice on taking photos. I’ll take some new pictures and post them. I originally posted this observation as Bjerkandera adusta and then decided to change it based on some obs. I have seen. Perhaps I should have retained the original posting. I’m basically trying to id fungi without a formal education except for a few biology courses. need to learn to dissect and study mushrooms.

With tiny pores?

I’m not sure it’s a Kretzschmaria… The grey surface on K. deusta should be a dusting of microscopic conidia, not an even surface of little pores. Are there perithecia inside the darker tissue underneath? The inside, aside from being flat and not zoned, should look much like your Daldinia, being full of little round vials of spores. It would be really helpful if you could get a slightly clearer picture. Have you tried setting your camera to a couple seconds delay, and standing it up in front of the sample? That’ll keep any jiggle out of the picture, and is a great way to get clear shots in low light (where you need a longer exposure).

If it’s covered in pores, I’d be more apt to think it’s a crustose resupinate polypore basidio of some sort. And that is not my group specialty, but if it IS a polypore, we can propose to name it as a Polyporaceae, and someone who’s as excited about custose polypores as I am about the Xylariaceae will see it and help ID it.
