By sight and texture. I haven’t scoped it out yet. It’s on the list. However the only other thing I could see it being is trametella gallica.

Thank you, Chaelthomas.

May I ask what specific criteria you used to determine T. hirsuta?

I examined two spore samples, one from material collected 7-16-17 and another from material collected 9-8-17. The one photo (7-16 8) shows elliptical spores with lengths up to about 5.5 microns. The spores I examined from material collected 9-8-17 looked the same (lengths peaking at about 5 microns). T. hirsuta spores are reported as longer, thinner, and with cylindric shape.

I am attaching two additional photos. The spore photo labeled 7-16 8 is a bit better focused than the one labeled 9-8 3. The photo labeled 7-20 2 is not very well focused. But, in the lower left there’s a cluster of fruit bodies with fairly well developed “caps” and thin bands of darker color are seen. This looks much like the examples seen in 9-8 1 and 9-8 2 (from which the samples provided were taken). Some of the fruit bodies I observed were broadly attached patches with very hairy flaps, and no observable hymenium. But others that had better developed “caps” (also very hairy on the upper sides of the flaps/caps) showed angular to maze-like pores on the downsides of the caps/flaps.

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?
