taken 10 days after the initial collection; same exact location.

I wetted these caps and the surfaces did not become viscid, just a little slippery. After an hour in the fridge they were dry and slick/polished again.

My collection had dry caps also but were also collected during a period of dry weather. I brought some home and left the caps soaking in water and they were very viscid after.

Thanks Herbert.

The mushrooms in the collection seen here did not have viscid caps. But they were collected during a period of dry weather. The caps were smooth and polished.

Dave, they may be conspecific…

.. I was going by the info presented by Micheal Kuo at mushroomexpert.com. He states that C. prunulus var. orcellus is stark white in color with a smooth viscid cap rather than slightly fibrillose. The picture he presents of this variation also shows slightly pink gills in maturity (since the spores are pinkish this would make sense). It would be interesting to see any molecular work that has been done; I was just throwing the name out there as more of question that needs to be answered.

Thank you,

Herbert, what are some features…

that distinguish var. orcellus? Judging from your MO post of this species variety it looks to me like the gills stay white for a long time. My collection seen here featured white non-decurrent gills on the young ones, but pinkish decurrent on mature mushrooms.
