Karstenia 47: 5–16, 2007 Clavarioid fungi of the Urals. II. The nemoral zone ANTON G. SHIRYAEV SHIRYAEV, A. 2007: Clavarioid fungi of the Urals. II. The nemoral zone. – Karstenia 47: 5–16. 2007. Helsinki. ISSN 0453-3402. 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 fi rst 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 an more rare species (47.8% / 38.2%). Species like Clavulinopsis aurantio- cinnabarina, 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 briefl y described and descriptions of the new and rare species for Russia are given.

The fi rst one (No. 1) the Perm region (hemiboreal zone), Sverdlovsk is a mesic spruce (Picea abies) forest with elms region (northeastern part of hemiboreal zone), (Ulmus laevis, U. scabra), maple (Acer plata- Chelyabinsk region and Bashkiria Republic noides), linden (Tilia cordata) and fi r (Abies (eastern part of nemoral zone) and Orenburg re- sibirica). Two of the localities (No. 2 and No. gion (southeastern part of nemoral zone). 4) are fi r dominated herb-rich forest with linden, Fig. 1. Locations of the research area. Materials and methods The material was collected by the author during ten years (1996–2005). Most of the species were collected in the forests and some were obtained from moist chamber cultures of various substrata, especially from dead herbs and leaves. For each locality an effort was made to examine the main types of microhabitats where fruit bodies of clavarioid fungi might be expected. Nearly one hundred moist chamber cultures were prepared as described by Härkönen (1977) and maintained for one month. The taxonomy mostly follows Hansen and Knudsen (1997) with some modifi cations according to Corner (1950, 1970), Parmasto (1965), Berthier (1976) and Jülich (1984). The genera Typhula Fr. and Pistillaria Fr. are treated according to Berthier (1976), and the genera Clavariadelphus Donk and Macrotyphula R.H. Petersen follow Petersen (1972). The corticioid genera Ramari- cium J. Eriksson, Kavinia Pilát and Clavulicium Boidin are excluded, as well as the cantharelloid genus Gomphus (Pers.) Gray. The nomenclature of vascular plants is according to Czerepanov (1995). The authors of species names are found in that publication and are not repeated here. In this paper the epithets “fi r” refer to Abies sibirica, “spruce” to Picea obovata, “pine” to Pinus sylvestris, “aspen” to Populus tremula, “maple” to Acer platanoides, “oak” to Quercus robur and “elm” to Ulmus spp., respectively. The list of species (Table 2 ) below is mostly based on my own collections and it shows the abundance of each species as well as the substrate(s) in each locality. In the text rare and new species to Russia are described. The specimens are deposited in the mycological her- barium of the Institute of Plant and Animal Ecology of the Russian Academy of Sciences in Ekaterinburg (SVER).
