Gills and white context make me wonder whether this is actaully a Cort… maybe a Hebeloma? Shiny dry caps with inate ratiating fibrils. Awaiting spore print.

I see the similarity… the halo.

Yes, very nice.

Thank you for checking. Yes, although weak in this particular case, this is a very typical reaction for sect. Variecolores – notice particularly the “halo” – the stronger peripheral discoloration. I have many examples. Here is one:

A cort

A cort in the Variecolores group. If you drop a bit of KOH on the context it will turn strongly yellow.

Dave, Hebeloma can fool you for a cort and it even fooled me the other day, but if you SMELL it it will tell you – the Hebelomas have a distinctive and strong raphanoid (like dry leaves and more) odor, detectable in almost all cases.
