Introduction Various species of macrofungi grow in the wild over most of the year due to the mild climate of Mediterranean Turkey (Gezer, 2000; Öztürk et al., 2003; Gezer, 2008). Turkish people do not have sufficient information on the edibility of macrofungi. They use unreliable identification methods passed down from grandparents. Poisoning and deaths have been recorded from time to time when people cannot distinguish edible from poisonous species using basic morphology alone (Işıloğlu & Watling, 1991; Işıloğlu et al., 1995; Işıloğlu et al., 2009). Entoloma clypeatum (L.) . (Figure) Description: Pileus 3-12 cm across, coniccampanulate when young, later convex to plane and often undulating, usually with an obtuse umbo, surface slightly hygrophanous, smooth, silky, medium to dark brown
