Yellowish- or pale-green patches o fliverwort Odontoschisma macounii grow on peatyfine earth on wet calcareous rocks. More often this species occurs as singular shoots among other bryophytes Seraya Island is occupied by extensive bare rocks where open bryophytes communities are widespread. Large stones or dry rocky are occupied by scattered mats, small cushions and short turfs o f mosses Andrea rupestris, Schistidium spp. and Racomitrium s.I. Wet rocky substrata are favorable for many bryophytes. Pohlia cruda, Barthramia ithyphylla, Plagiothecium denticulatum together with Gymnomitrion concinnatum and Diplophyllum taxifolium grow in the moist rock crevices and hollows. Biyitm species prefer fine eaith on rocky ledges. Closed mountain birch forests and even scattered birches have a profound influence on microclimate under their crowns affecting cryptogamic vegetation. Even a closed layer of dwarf shrubs forms a microclimate, which differs from open soil. Bryophytes form a dense Closed thicket under a coppice of mountain birches, junipers and heath in subalpine and lower alpine zone where species such as Hylocomium splendens , Plewozium schreberi, Polytrichum spp. and Ptilidium ciliare are very SteppedMoss or Glittering Wood-moss ( Hylocomium splendens) is one o fthe most well known among the mosses. It is common andmay be abundant amongst grass and heather on heatliland on terrains, in subalpine and alpine zone. Whilst usually occurring in acidic habitats, it may sometimes befound on calcium-rich rocks 82
