could find http://www.cybertruffle.org.uk/... I also note that the descriptions I have seen for G. liquiritiae say it grows on conifers ( acouple out of 10 say “& hardwoods in the southern US”):( I can’t find where I read about the violaceus tones, maybe psilocybin mushrooms of the world? Maybe I dreamed it. truth is, is was originally described from a European country, so in all likely-hood, it doesn’t even occur in the us :(
In regards to the pileus structure

Of the pins. I’ve studied both the pins and mature specimens under a lens. They start off so densely appressed that they look glabrous. Under a lens you can see the fibrilis. As they mature the pileus gets bigger but that outer most layer just kinda stretches and breaks up into fibrils that merge together in tufts. As it drys the tufts stain purple and become semi erect.

G. liquiritiae originally because of one of the pics Kuo uses for the species page, I think he got it wrong. Can you link me or tell which book you see the description of purple bruising in? I can’t find that anywhere its been driving me nuts. If you look again at the second obs I linked you’ll see in the gill shot that the stem has a massive purple stain. The gills edges all stained when I got it out of the tackle box at home. I’m 90% sure they are the same. I’ve been going back to the patch in obs one for over a month… They fruit over and over and over.

The pins in obs1 start vinaceous then turn tawny yellow then orange… All the while staining purple where touched. Especially the pileus margin and gill edges.

One other thing I noticed… I’ve never found them on big logs, just limbs and one skinny log I’m starting to think was maple.

Rich scoped obs1 and like he mentioned the microscopy points away from liquiritiae. I don’t think these were described by Hesler. The purple staining just seems too noticeable a feature to go unaccounted for..

There were a couple of these on shroomery this month. One from Ohio and one from Michigan.

I read what Gsharp said, It seems he agrees? Look at the pins in the last pic,( of my obs) purple and cracking, I just don’t see that in yours, but I do see it in the description of G. liquiritae. those pins seem glabrous to me, but not the older specimens, necessarily. I may have a mixed collection as well :(

I agree

that they are the same as the first observation you linked, but I think the second ones appear different. the specimens in my obs, display prominant lilac tones even in the pin stage all the way up to advanced adulthood. Your second obs. doesn’t show that as far as I can tell. I no longer live in the locale (Ill.) which did you have him scope, the first or the second? My confidence on my obs being G. liquiritae is not high, it was based on;
A; It displays blue bruising (and is therefor probably active)
B) It was found in Illinois( where Micheal Kuo describes G. Liquiritae from, on mushroom expert)
C) macroscopically they appear to be similar to the ones Kuo shows on his page. I know you guys don’t want to hear it, but I question the accuracy of Heslers monographs. I equally or greater question Kuo’s page.

I KNOW my obs are not liquiritiae, thanks to your micrography. But I can only think that leighton’s are not, as I don’t have them in hand.

These look an awful lot like the ones I’ve been collecting.

not to mention…

If you collect any more purple staining Gymnopilus could you dry and store them for future microscopy? I don’t think these are G. Liquiritiae for a variety reasons.

Let me know what you think. I thought my collections were glabrous at first until I looked at them under a loupe.
