ResumoSchistostega pennata (Hedw.) F. Weber & D. Mohr was found for the fi rst time in Poland at Ustron in the Western Beskidy Mts by Milde (1852). In April 2006, during a botanical excursion to the Wąwoz Wodospad ravine near Ciezkowice in the Pogorze Ciezkowickie foothills, the author found a new locality of this moss, which is rare in the Carpathians. This is the fi rst locality of the species in this region and its third locality in the Polish Carpathian foothills. Schistostega pennata is the only representative of the family Schistostegaceae in the world (Corley et al. 1981; Ochyra et al. 1988, 2003; Crosby et al. 1999). It is a characteristic species, diffi cult to misidentify, with its distichous confl uent leaves and luminescent protonemata. In Europe, Schistostega pennata grows mostly on soft, often crumbling soil in dark recesses of shaded lanes, under overhanging banks in woodlands and quarries, in entrances of caves and quarries, in deep crevices between granite blocks or sandstone walls. It is adapted to minimum light supply and is moderately cryophytic. It prefers wet and acid substrates. It can grow on fl at ground or on steep walls and slopes up to even 94 inclination (Dunk 1987; Diersen 2001). In Europe, S. pennata is a dominant species in communities belonging to the association Schistostegetum osmundaceae Giacom. 1939 in the order Diplophylletalia albicantis Phil. 1963 and class Cladonio-Lepidozietea reptansis Jez. & Vondr. emend. Marst. 1992 (Diersen 2001). In the Polish Carpathians, Schistostega pennata has so far been found only in deep sandstone crevices and on soil between roots of upturned spruce. Here it prefers a shaded, humid and acid habitat. SCHISTOSTEGA PENNATA (BRYOPSIDA, SCHISTOSTEGACEAE) IN THE POLISH CARPATHIANS (POLAND)
