Remarks (internal):Entoloma sepium is missapelled as E. saepium, R. saepius etc. (see Noordeloos in Persoonia 12: 459. 1985). It is easily distinguished by the orange-yellow tinges of the flesh being bruised, the pallid, not hygrophanous pileus, that is usually very regularly shaped. It is edible, but it may be confused with Entoloma niphoides and pale forms of Entoloma clypeatum, that occur in similar habitats, and often the species are found to grow close to each other. It is therefore recommended to collect only typical and fresh specimens to eating.
