Do you recognize this one?
No unpleasant smell, no irritating taste.
Spore print "pale pinkish buff".
They were growing in a group and also by themselves.  The largest was growing by itself and the cap measured 2.75". In this group picture the largest had a 2 & 1/8" cap.

It looks like a Clitocybe but I was confused by that brown looking stains on the one in the middle.  At first I thought  it might be spores from the one above it.  I finally got a spore print and it came out very much that color but lighter.  Reading the guide they mention that Clitocybe irina stem bruises brown or turns brown with age.  So that brown might be on the cap due to contact with its neighbor.  I also removed some leaves to expose the stems for the picture.  That bruising might account for the brown stain on the stem.

This one has about a 1/2" cap.

Here is one with mature gills.

Here is the tip of a stem.

Spore deposit on stem or more likely, bruising brown?

Side view showing the sunken dome in the top of the cap.

This section view also shows this distinctive feature.

Where does the cap end and the stem begin?

I checked through Mushrooms of Northeast North America by Allen Bessette and came up with Clitocybe irina.
What about it George, do you agree?  Anyone else?

I had two replies, so far.  James thinks it is Clitocybe but not irina because of the decurrent gills.  I think this is an optical illusion.  Look at the sectional view.  The cap edge rose up above the center of the cap to form a vase shape.  If you try to estimate where the cap flesh leaves off and the stem begins I can see that it could be considered subdecurrent.  Also, I now think, that those brown spots on the stem and cap are from bruising rather then spore deposits.  That is a characteristic of irina.

Dave thinks it is Sweetbread.  In my guide I do not see any mention of the depressed dome feature.  Also the spore print would have to be "salmon pink".  The spore print came out as a pale tan with a pink undertone.  I think the "pinkish buff" describes it better then "salmon pink".

Maybe I discovered a new mushroom and will go down in history? :o)

Maybe that is the difference between a beginner and an expert.  A beginner is not afraid to hazard a guise on an ID.
