the genus Melanoleuca is badly in need of revision, and the epithet melaleuca has caused a lot of confusion, just to mention one of them..
If you look at Murrill’s picture and description, I think you will agree that it’s another species than yours:
http://www.cybertruffle.org.uk/... (pict. 4)
(M. stridula sensu Métrod and Kühner, and M. graminicola sensu Favre are probably synonyms).

What you have found, looks similar to one I use to key out as Melanoleuca exscissa – but I suspect that there are more than one species hidden there.

M. melaleuca sometimes has harpoon shaped cystidia according to some authors according to this web page. I would like to find out what species it is since its so common. I have a dried sample.

Where are the warted spores?

Are we sure of Melanoleuca even? Where are the amyloid warted spores? The spores I can see, seem to be smooth? What was the reagent?

melaleuca is out of the question

It’s one of the few that lacks cystidia. I could make a wild guess on Melanoleuca excissa, but some pictures of the mushroom would have been nice, at least notes on colours and size of cap and stem – and spore size too.
