I’m happy it made it intact and it was fun doing the small amount of documentation on the subject.
Thanks again for your interest Christian and also the speedy ID and reply.

Hi Rand – thanks for the excellent notes with your specimen!

My inspection of the fruitbody suggests to me that this is Callistosporium luteo-olivaceum.

The photos looked more greyish-brown, but looks more greenish-yellow in person and in some photos.

The yellow gills have developed a few dull reddish stains, which sometimes happens with this species. The stipe is flattened and cartilaginous, and your notes indicate that it was on a coniferous stump, which also fits well for this species.

I will drop a bit of KOH on it to look for the red reaction.

It will be added it to the Fungal herbarium at UCSC’s Ken Norris Center.

It was in a backyard, stump maybe 16" tall, 30 feet from current firepit.
Yes I can collect tomorrow, would you like it Christian?

Was it near burned ground? Any charcoal around?
Can you get dry a specimen of this?
