Rubroboletus le-galiae is reported for the first time from Poland. Macro- and micromorphological characters of the species are described and illustrated based on the study of material collected at three microlocalities in Łężczok reserve (SW Poland). The delimitation of R. le-galiae from related species of the genus Rubroboletus (R. satans, R. rubrosanguineus, R. rhodoxanthus) is shortly discussed and the knowledge of its ecology and distribution is briefly summarized.
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
Chamonixia caespitosa Rolland, has been recently found in Poland for the first time after 1945. The basidiocarps, partially exposed from the humus layer, were found in two localities: in the spruce forest in the Polish Tatra Mts., at the elevation of 1540 m a.s.l., and in the mixed forest with spruce and fir in the Beskid Niski Mts. at the elevation of app. 400 m a.s.l. The description of the Polish specimens generally agrees with descriptions of the specimens found in other Central European countries. The roundish to tuberculate basidiocarps were characterized by the presence of highly reduced stipe, whitish colour of the peridium changing rapidly to blue after exposure to air, small, complete or incomplete columella and brown, spongy gleba. Typically 4-spored basidia were present which produced ellipsoid, brown spores with the ornamentation in the form of rough, interconnected ridges. Taxonomic position, ecology and chorology of the species, the ontogeny of basidiocarps and description of ectomycorrhizae are summarized in the paper.
Phylogenetic analyses place Octaviania asterosperma in the Boletales, with Leccinum being the closest relative. Results of the structural investigation of O. asterosperma ectomycorrhiza with Fagus confirm this systematic position. In Europe the species is an ectomycorrhizal partner of broad-leaved trees, such as Carpinus, Corylus, Fagus, Quercus and Tilia. This paper aims at presenting the new data to the distribution of O. asterosperma in Central Europe. The description of the basidiocarps discovered in Poland in the recent years is also given, together with evidence for the parasitic relationship of Sepedonium laevigatum with O. asterosperma. We also present the information concerning all known localities of the species in Poland and its distribution map. Data on the ecology, distribution and status of O. asterosperma in Europe, and some structural aspects of basidiocarps and spores, are also summarized.
Scleroderma septentrionale Jeppson was fi rst discovered in Central Europe in the Puszcza Kampinoska primeval forest (Central Poland) over 40 years ago. We found two new inland localities of this rare species in southern Poland: on natural inland sand dunes of post-glacial origin (Pustynia Błędowska) and at an anthropogenic site on sandy soil polluted by heavy metals (Olkusz, in the vicinity of the Bolesław Mine and Smelter). The basidiocarps occurred under willow and birch or pine and birch. The new localities are approximately midway between two previously known inland stands in Central Europe (Puszcza Kampinoska forest and the Zahorie region in Slovakia).
