Here's the other "form" of that white funnel-capped mushroom. These were growing in grass among wood debris in quite large numbers; CAP 1-3" wide, watery creamy to whitish, margin strongly rolled under, splitting radially; GILL creamy, cross-walls conspicuous, often forking, somewhat thick, very decurrent; STIPE maybe 1/4" thick, solid; SPORES whitish of some sort presumably.
