The exploration of hypogeous fungi in the Carpathian-Pannonian region speeded up in the past decades, owing to the widespread of truffle hunting with dogs. As a result, not only several new species were found in the region, but our view of the frequency of truffles also changed fundamentally. It became evident that Tuber aestivum, T. brumale, T. macrosporum, T. magnatum, T. mesentericum and Mattirolomyces terfezioides can be collected in commercial quantity. Among the dog preferred hypogeous fungi (DPH) several species, earlier believed to be rare like Octaviania asterosperma and Stephensia bombycina, also occurred. The taxonomic alterations and revisions brought about changes in the list of hypogeous fungi, and further changes are expected from molecular taxonomy research on a number of genera at present.
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.
