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.
The paper gives a survey of biodiversity of noble fir (Abies procera) stands in Rogów Arboretum on the background of environmental data. Noble fir is native to the mountains of north-western United States. During the study in the Rogów Arboretum we have found 53 taxa of vascular plants and mosses, 51 taxa of macrofungi and 112 of invertebrates in Abies procera stands. The documented biodiversity of planted Abies procera stands has been commented with respective data from natural habitats.
