There were several 'bunches' of these...pure white stems...a thin skirt...light yellow to orangy-brown cap...tight gills..... small caps...no wider then 3cm across. I was unable to get a spore nor did i notice much of an odor....they were growing with moss and another type of mushroom I'm still looking for an ID to. Found in a light forest along the Missouri River...on a 'flood zone' area....In Missouri
From the photo angle, it looks like it is growing on wood. Do you recall if it was, and if so, whether it was likely to be hardwood or conifer, what trees were generally around?
All the different mushrooms of this variety were growing on dead wood off a 'flood zone' area up from the Missouri River. This area has maples, cotton woods, young elms and very few evergreens....the particular piece of wood this bunch is on has actually been laying there for such a long time there was very little of the actual smooth under-bark area left so I wouldn't be able to ID the type exactly to u. Sorry.
I ran through matchmaker a couple of times http://www.pfc.cfs.nrcan.gc.ca/cgi-bin/matchmaker/matchmaker.asp and eliminated lots of things, but nothing leapt out as a potential winner. Galerina still looks like a good choice. If you thought it might have white spores, Armillaria might be a good key to run through.
wow...that's a lot of images........and wonderful to go thru! i'll have to click back for more referrencing. i didn't save a specimin for photographs as i hate to 'destroy' beauty. i'd actually? thought it was possibly 'deadly galerina' but i'm not so positive now as i've looked at other images of said mushroom. thanx for that link though!
