The Snowy Waxcap usually has an ivory or creamy-white cap, with a slightly greasy texture, but not sticky.  The centre of the cap may be darker in colur, and brownish or yellowish form do occur.  Specimens infected with a mould Metarhizum marquandii may be stained purplish.  The few wide spaced gills are decurrent (run down the stem).  The cap becomes flattened and often upturned as it matures.   

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) but these have more crowded gills
