Abstract: Cololejeunea chuahiana and Microlejeunea nyandaruensis are described and illustrated, as species new to science, collected in the subalpine moorland belt of Aberdare Mountains (Kenya), where both inhabit the tiny twigs of Erica species and of Cliffortia nitidula R. E. & T. C. E. Fr. Their taxonomic position and affinity to related species is clarified.

Abstract: Chrysophycean stomatocysts from the small, very threatened peat bog near Budzyń (Kraków-Częstochowa Upland) were investigated using light and scanning electron microscopy. Twenty-eight different cyst morphotypes (unornamented stomatocysts, stomatocysts with hooked projections in the collar region, and stomatocysts ornamented with spines) were recorded and documented with drawings, photographs and descriptions following International Statospore Working Group (ISWG) guidelines. One stomatocyst, Stomatocyst 1 Cabała, is described as a new morphotype.

Abstract: Two new localities of Carex curvata Knaf in Poland were found. The species has not been reported from this country for nearly a century. This paper gives the phytosociological characteristics of the newly found stations, a map of the distribution of C. curvata in Poland, a description and drawing of the species, and a key to related species.

Abstract: The distribution of the very rare and threatened fern Woodsia alpina in the Polish and Slovakian Tatras is reviewed and mapped. The species is scattered between 1100 and 2600 m a.s.l. It occurs in the Western Tatras on dolomite rocks and in the High Tatras on mylonitized granites, growing mainly in crevices of very steep rock walls. The populations are very small, usually comprising a few plants. The threat to them and conservation measures are discussed.

Abstract: Andreaea nivalis Hook., known in Poland only from the Tatra Mts previously, is reported from the Karkonosze Mts; this is the first record for the whole range of the Sudety Mts. The distribution of the moss in Poland is reviewed and a brief description of the site in the Karkonosze Mts is provided.

Abstract: The mycoparasitic auricularioid fungus, Naohidea sebacea (Berk. & Broome) Oberw., was found in Poland on the old stromata of Botryosphaeria dothidea (Moug.: Fr.) Ces. & De Not. This is the first Polish record of this peculiar fungus since G. Bresadola's description of Platygloea miedzyrzecensis Bres. in 1903. Botryosphaeria dothidea is a new host fungus for the mycoparasite.

Abstract: Geranio phaei-Urticetum dioicae, a poorly known association of nitrophilous saum communities occurring in the mountains of Central Europe was characterized based on 39 phytosociological relevés. Its ecological requirements and distribution in Poland and Central Europe are presented and discussed. Five new subassociations of the Geranio phaei-Urticetum dioicae (G.-U. arrhenatheretosum elatioris, G.-U. typicum, G.-U. festucetosum giganteae, G.-U. senecionetosum fuchsii and G.-U. rumicetosum alpestris) have been distinguished on the basis of differing species composition.
