SPECIMEN EXAMINED. — Turkey (Giresun province): Dereli district, Kümbet plateau, streamside, on moist soil, in the forest ( Picea orientalis (L.) Link), 40°33’04”N, 38°27’18”E, 1610-1630 m, 11.VII.2019, leg. H. Erata, M. Alataş and N. Batan, KTUB[KTUB 1607].

ECOLOGY. — Pohlia lescuriana usually grows on damp clayey soil on banks by streams, ditches, reservoirs, paths, on woodland rides and in fields ( Smith 2004). In addition, P. lescuriana can be found on soil in exposed and disturbed habitats ( Ireland 1982). Turkish specimens collected in Kümbet plateau, on damp soil, streamside in area of Picea oritalis forest. It was found together with Mnium spinosum (Voit) Schwägr , Philonotis fontana (Hedw.) Brid. , Brachythecium albicans (Hedw.) Schimp. , Ptychostomum moravicum (Podp.) Ros & Mazimpaka, P. pseudotriquetrum (Hedw.) J.R. Spence & H.P. Ramsay var. pseudotriquetrum and Marchantia polymorpha L.
