Snowy Waxcap - Cuphophyllus virgineus

Snowy Waxcap has an ivory or creamy-white cap, with a slightly greasy texture, but not sticky.  The few wide spaced gills are decurrent (run down the stem).  The cap becomes flattened and often upturned as it matures.  Occasionally darker specimens are found and there are several varieties described. 

The Cedarwood Waxcap (Cuphophyllus russocoriaceus) is very similar, but strongly scented of cedar oil, as in the wood of some pencils. 

It can look similar to some white Funnels (Clitocybe) - check for the widely spaced gills and wavy, irregular stipe
