The caps on these are certainly more fleshy and flimsy that the gymnopilus I found here before. The big cap just half melted when I took the original spore print under a bowl, and the big gyms I found here before were not like that. Thanks for assisting me in this….

The brownish stains in the middle and lower right of the paper…

appears to fan out in segments that approximate gill alignment. So I think there may be spores involved there. But it does also appear that liquid due to decomposition has played a role in producing what may be seen on the paper.

The mushroom reminds me more of Tricholomopsis. But like I wrote previously, I have been fooled by the Tricholomopsis/Gymnopilus look-alikes.

Here’s the caps two days after collection, I left outside. So the gills have turned this color from the creamy color when collected. The poor resolution photo of the spore print included. The spore print was taken when very fresh. Maybe if I do it again it would leave a more robust deposit. Leave this one to the experts, thanks…

possibly stain from pigment?

These mushrooms were quite moist/fleshy and I may not have looked closely enough to distinguish what might have been only orange liquid creating a relief of the gills on the paper (not much in fact), with an actual spore print underneath concealed by the white paper. I’ve noticed before that white spore prints, even “creamy” are hard to see on white paper. gymnopilus I have printed before here in Japan were profuse, thick prints, not like this, no question. The prints on this specimen were very spotty, leaving me to suspect that I may have misinterpreted orangey juice as spores?. Thanks for the guidance. I sort of thought gymno at first as they were growing mostly out of old stumps.

The gills look very pale…

for an orange-spored mushroom. Shinto, would you say the photos accurately show the gill color?

In my own experience here in Pennsylvania USA, while in the woods I have occasionally confused species of Tricholomopsis with Gymnopilus species.

I suppose Pholiota may also be considered here.

Can you photograph the spore print?

spore print is orange and not creamy white. on these. The pictusre of Tricholomopsis I could find show, “plum” colored on the margin of the cap and yellow at the center, with some almost all “plum” colored.. It does look a lot like it , though, maybe there is an orange spored one here .
