taken 9-8.

Maybe Trametes?

Okay, Chaelthomas.

The “flap” with the poroid underside seen in the photos is in my dryer. You may have this. I’ll need your mailing address.

Thanks for the offer.

You can

Send these off my way with any information you have on them.
I can check them out in the scope and see whats going on.

I’d say Trichaptum makes about the most sense, so far.

Fertile surface on the piece seen in several of the photos appears to be poroid with walls elongating irregularly and toothlike.

I got a thin white spore print and mounted in Congo red. Best photo I got wasn’t very clear. Maybe a dozen or so spores could be seen. They appeared to not have the cylindrical shape reported for species of Trichaptum, rather elliptical ~4.5-6 × 2.5-4. But this may be on account of these spores not being oriented to favor viewing in profile.

I’m sure I’ll visit this spot again within the next week. I know just where to find this old beech log. Maybe a little more growth will provide a clue.

taken 7/16.

Context pliable but not rubbery/stretchable. Tough/resilient.

KOH instantly dark olive on shelf-like part.

Spores dropping, check tomorrow.

Second look… looks like a polypore.

I didn’t think K. deusta was the correct ID here… just kinda “in the ballpark”. I believe I re-found this fruiting today. Visited the site (one of my favorite… shhhh… Bolets edulis spots). Still need to compare photos from then and now. I brought home some material, so… anybody interested? Actually, I’ve got a few other things destined for the dryer, so I’ll throw a piece of this in.

i see now

that this is reflexed, so it is either a stereoid or something with very-small or not-yet-developed pores, like Gloeoporus. I’m leaning toward the latter. post more photos when it’s more mature?

Good question.

No pores are visible anywhere in the photo. I guess I was thinking along the lines of something like Stereum. But I think this is likely incorrect. Maybe something closer to Kretzschmaria…?

pores where?
