This paper describes, illustrates, and maps a new regional bramble species occurring in the Myśliborskie Lake District in NW Poland. It represents the series Mucronati, which until now has never been recorded in this part of Europe. Locally it is the common plant and usually can be found in pine plantation established on former farmland.
Leccinum variicolor Watling is widespread but it is a rare species in Poland and some other countries, and is either protected or red-listed. This paper describes the morphology and ecology of L. variicolor as well as its distribution in Poland. Key words: macrofungi, threatened fungi, distribution, ecology
The paper presents the results of studies of Xanthoparmelia pulla group in Poland. The morphological and chemical analysis of herbarium materials confirmed the presence of four species of this group reported from Poland before. The study however, revealed considerable changes it the partiuclular species distribution. X. verruculifera, so far considered the most endangered species in the country, turned...
Habitat studies were conducted on three rare plant communities dominated by Nuphar pumila, Nymphaea candida and Hydrilla verticillata in lakes of north-eastern Poland. The comparison of habitat properties of these three types of phytocoenoses with those of Nuphar lutea common in the area under study was also performed. It was demonstrated that the plant communities studied were ecologically distinct...
A new site of Biatoridium monasteriense was discovered during a lichenological investigation in Białowieża National Park. The paper presents information on the distribution of this species in Poland.
The study presents recent data on the distribution of Fellhanera gyrophorica (Pilocarpaceae, Ascomycota) in Poland, a rare lichen with a crustose, usually sterile thallus. Both previous and new localities of the species are presented with data on its ecology and general distribution. Furthermore, this paper provides detailed results on floristic investigations of the species in the forest areas of...
The distribution and ecology of charophytes in Lubelszczyzna (Eastern Poland) is described based on herbaria collections, literature data, and the author’s own investigations. Maps showing the distribution of all 22 charophyte species identified so far are presented, as well as the details of habitats ecology. Some data on species frequency, conservation, and threats are added.
The descent of some mountain species into the lowlands is an interesting phenomenon in plant geography and ecology. The main purpose of the present study is to update the list of mountain species for the Silesian Uplands and to provide a synthesis of the knowledge accumulated to date on the habitats for their occurrence, a possible origin and their distribution patterns. In the present study, both...
