    Opis:
    Dicranochaete quadriseta (Korš.) Nov. and Pop. was collected during investigations of algae from mountain peat bogs of the Sudeten Mts (Poland). The paper describes the morphology, taxanomy, geographical distribution and ecological conditions of this species. This very rare species was found in an oligominerotrophic peat bog called "Topieliska-Zieleniec" near Duszniki (Orlickie Mts).

    Opis:
    A preliminary red list of threatened lichens of Lower Silesia (SW Poland) is presented. Species have been valuated according to the Red Data Book Categories (IUCN). The list comprises 602 taxa (ca. 60% of the whole lichen flora of Lower Silesia). 52 species are considered as rare (category R), 84 - as vulnerable (V), and 63 species - as endangered (E). The Silesian lichen flora is characterized by great numbers of taxa with extinct (Ex -140 taxa), and indeterminate (I - 263 taxa) categories.

    distribution
    Opis:
    The distribution of four species of the genus Vulpia [V. myuros (L.) C.C. Gmel., V. bromoides (L.) S.F. Gray, V. ciliata Dumort. and V. geniculata (L.) Link] reported in Poland has been studied. Currently, V. myuros and especially V. bromoides are very rare species, and their greatest concentration can be found only in the Lower Silesia region. The number of their localities decreased after 1950 and it seems resonable to include both species in the "red list" of threatened plants in Poland: V. myuros in the EN category, V. bromoides in the CR category. V. ciliata and V. geniculata are very rare ephemerophytes and their localities not confirmed during ca 60 years are of historical interest only.

    Opis:
    The paper concerns a very rare and poorly known species of green alga Chlorodiscus natans Petersen & Hansen, discovered in the peat bog "Brzeźnik" near Bolesławiec (Poland). This is the second stand so far discovered in the world. The collected material allowed complementing the knowledge on organization of colonies, morphology and way of hair development. The remaining features, particularly the structure of the cell, are in concordance with the hitherto diagnosis of that species. The paper presents problems connected with the taxonomic affiliation of the species and describes the ecological conditions of habitats occupied by this alga.

    Opis:
    The paper provides the use of self-organizing feature maps for determination of soil properties in its initial stage of development formed of massive rocks and how SOFM can be used for the study of environmental objects. The study area was Lower Silesia (Poland) overgrown with common, unique and protected vegetation of lichens, bryophytes and vascular plants. The parent rock of the studied soils consists of Miocene volcanites from the middle part of the Sudety Margin Fault. Soil samples were collected from 20 sites. The soil reaction (pH) and concentrations of Cd, Co, Cu, Fe, Mn, Mo, Ni, Pb, S, Ti, Zn in surface soils were analyzed. Statistical analysis was carried out by one-way ANOVA. The SOFM was used to demonstrate the non-linear ordination and visualization of soil properties. The SOFM showed the influence of parent rock on soil chemical properties generated by it. SOFM appeared to be effective and proper/fit for phenomena and processes taking place in natural environment and is useful in ecology and ought to be taken into account as a possible tool of estimation of various plants and their biotopes. The model can be useful as alternative techniques in modelling the ecological complex data, and provide a novel framework for the discovery and forecasting of ecosystem structure and behaviours in response to environmental changes.

    Opis:
    The results of studies of the mycorrhizal status of plant species spontaneously established on the soda heap located in Jaworzno (Upper Silesia, Poland) are presented. Additionally, the species of arbuscular fungi of the phylum Glomeromycota extracted from field-collected rhizosphere substrate samples of the heap are showed. Arbuscular mycorrhizae were described in 17 plant species. Five Glomus spp. were recognized in the spore populations of arbuscular fungi isolated. The investigation presented in this paper for the first time revealed Centaurea stoebe and Trifolium montanum to be hosts of arbuscular fungi.
