Found growing in a crevice of a log, probably coniferous (Although I don’t recall). The picture angel was awkward and hard to take.

I found some interesting specimens in NY

The forest this was found in has a lot of Panellus stipticus, this one was intriguing to me due to having 15 caps from a single base. It did not glow, it is the first Panellus stipticus that I have found that neither the fruit nor the mycelium glowed.

The mycelium also behaves a little dfferently on agar.

I agree with Walt

these are just another example of the E/W divide. It’s what we call it out here…

The gill color in the picture looks variable, many of the specimens are more pale then a lot of the observations on MO, but a few of the larger ones seem like the same color as the observation you linked. The texture also looks suspect to me, but I didn’t check it in the field and am unsure if the photo is good enough to see it properly. When I found them I thought they were entirely immature due to their concealed location on the log (Hard to examine closely), I wouldn’t of seen them at all if I didn’t stop to take pictures of observation 67837. And I did not know about the bio-luminescence till today, I will be sure to attempt to observe it next time.

As for Omphalotus, I haven’t been able to get them to glow at all.

Could be a west coast/east coast variance

Gill color looks too pale to me. Stems are not as fuzzy. It looks very different to me but I have no other species name to suggest. Is your species strongly luminescent? Our local one is brighter than Omphalotus.I have read that the European variety does not glow at all.

I have learned that west coast mushrooms do not match the same named species in the east. Hygrocybe psittacina is another example.

Any reason you are doubtful? I’m curious as to what else it could be.
