Abstract: One hundred and eighteen clavarioid species are reported from the nemoral zone of the Ural Mts.. Eight of them, Ceratellopsis aculeata, C. terrigena, Lentaria corticola, Pistillaria quercicola, Ramaria broomei, R. lutea, R. subtilis and Typhula hyalina, are reported for the first time from Russia. The material consists of 1300 collections and observations, and according to these, the most frequent species are Clavulina cinerea, Macrotyphula juncea, Typhula erythropus, T. sclerotioides, T. uncialis and T. variabilis. These contain ca. 23 % of all observations, but only 5 % of all the species. In comparison with the boreal zone of the Urals, the nemoral zone consists less abundant species (1.7% / 14.6%) and more rare species (47.8% / 38.2%). Species like Clavulinopsis aurantiocinnabarina, Pistillaria quercicola, Ramaria broomei, R. lutea and Sparassis brevipes are considered to be relicts of Pliocen and Holocen periods. The most favorable habitats for the rare and relict species are discussed. The collecting sites are briefly described and descriptions of the new and rare species for Russia are given.

Abstract: Inventories of corticioid fungi (Basidiomycetes) were carried out on four permanent 400 m2 sample plots scattered over Belarusian Moraine Ridge. Selected coenoses belong to boreonemoral vegetation zone and the forests are dominated by spruce, aspen and oak, of Oxalis and Aegopodium types. The number of corticioid fungi in these forests was in average 37 species, which permits to evaluate Querco-Piceetum as the most species-rich forest type. The largest genera were Hyphodontia (5–7 species per plot) and Peniophora (3–4 species, respectively). In general, the more dead wood was produced by a host the higher was the number of fungal species inhabiting it. In this study spruce plays a minor role as a host for corticioid fungi (in boreonemoral forests), harbouring only a few species. Cluster analyses demonstrated that structure of fungal assemblages is dependent on the type of plant association, and in several cases also on geographical distance between the study sites.
