Remarks (internal) : Entoloma quadratum is very easy to recognize on its salmon pink to orange basidiomes and cuboid spores. It is widespread, and locally common in North America and Japan, and extends also in eastern Asia (Horak 1976, 1980; Noordeloos & Hausknecht 2007). It was reported as E. salmoneum (Peck) Sacc. from Kedrovaya Pad Nature Reserve by Vassiljeva (1973).
