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.
