As a result of field and laboratory studies, 73 species were identified. Seven (7) fungi belong to Pezizomycota and 66 to Agaricomycota. Of these fungi 55 represent new records for Forebalkan floristic region. Two (2) species includes in the Red List of fungi in Bulgaria: Clavicorona pyxidata (Pers. : Fr.) Doty, and Phyllotopsis nidulans (Pers. : Fr.) Singer. This paper presents the most up-to-date and extensive list of lignicolous macrofungi of mountain ridge Lisets, Forebalkan floristic region.

According to the physical and geographical characteristics is situated within the Stara Planina (Balkan) region (Georgiev, 1985; Yordanova et al., 2002). Climatically the mountain ridge belonds to Temperate-continental climatic Zone (Velev, 2002). The highest points is peaks Kamen Lisets (1073 m) and Cherti grad (1283 m). The study area is covered mainly by natural forest due to the prevailing climatic and edaphic conditions and limited timber extraction. The canopy vegetation of the study area is composed of mainly broadleaved and coniferous trees. The research area therefore is an ideal habitat for mycological studies. Тhe larger fungi of Forebalkan has been poorly studied. There have been only sporadic records of single species from neighboring areas, Central Balkan mountain and Central Balkan National Park (Burzakov, 1926; Hinkova, 1961, 1965; Stoichev, 1981, 1982, 1983, 1987, 1995; Stoichev and Dimcheva, 1982, 1984, 1987; Vanev and Reid, 1986). Summarized and supplemented information for fungal diversity of the Central Balkan National Park has been presented by Fakirova et al. (2000). Check list of Central Balkan Mountain includes 369 macromycetes were published from Fakirova et al. (2002). So far, detailed mycological study of the wood-decaying species of the southwestern slopes of Vasilyovska Mountain (Forebalkan) were conducted by Lacheva (2014). But there has not, however, yet been any detailed mycological research devoted to mountain ridge Lisets and its environs. The aim of this work was to determinate the lignicolous macrofungi of mountain ridge Lisets and make contribution to fungal diversity of Forebalkan floristic region, as well as Bulgarian larger fungi as a whole. MATERIALS AND METHODS The lignicolous macrofungi samples of this study were collected periodically from 5 localities in beech forest of eastern slope of the mountain ridge Lisets between 2004 and 2012.

Composition of plant communities consists of woody, shrubbery and herbaceous species. Most of the area is covered with beech forests, although gymnosperms forests also exist at lower elevations. Beech (Fagus moesiaca Cz., F. sylvatica L.) and Hornbeam (Carpinus betulus L.) are dominant species, sometimes forming mixed forest with Fir (Abies alba Miller), Scots pine (Pinus sylvestris L.), and oak (Quercus sp.) Liebl.). The stands of Black pine (Pinus nigra J.F. Arnold) and Scots pine are widespread in the western and southern regions of the lignicolous fungi collecting area. Deciduous forests interspersed with Acer sp., Fraxinus sp., Tilia sp., etc. Typical representatives of the shrub species are Crataegus monogyna, Prunus spinosa, Rosa canina, Sambucus nigra, etc. Moreover the forest is recognized well by Ostrya carpinifolia and isolated Pinus nigra, etc. (Bondev, 1991). Beech forest in that area lie at an altitude of 650 m to 1300 m, on terrains with differently exposition and incline, but predominantly exposed to the eastern, south-southwest or northwest. Collection localities 1. Community of Fagus sylvatica L., with participation of Quercus cerris L. in the locality Marino Korito, under Glozhene Monastery “St. George”, 850-950 m alt. 2. Community of Fagus sylvatica L., with participation of Carpinus betulus L. in the locality Komina, 850 m alt. 3. Community of Fagus sylvatica L., with participation of Pinus sylvestris L. below the peak Kamen Lisets, 1000-1050 m alt. 4. Community of Fagus sylvatica L., with participation of Abies alba Miller and Quercus cerris L. around the Glozhene Monastery “St. George”, 1000 m alt. Maria Lacheva .

Mezophylous community of Fagus sylvatica L., with single participation of Acer campestre L., Betula pendula L., Carpinus betulus L., Corylus avellana L., Populus tremula L., and Sambucus nigra L. in the locality Dragoychova shuma, 600-750 m alt. Determination, nomenclature and keeping of the samples Relevant morphological and ecological characters were recorded for the fungi, which were photographed in their natural habitats. In the herbarium, the fungi were further examined and microscopic characters were measured in Melzer’s reagent, 5% KOH, and H2O. Identification of the specimens was performed according to Michael et al. (1983–1988), Breitenbach and Kränzlin (1984–2000), Phillips (1981), Ellis and Ellis (1990), Hansen and Knudsen (1992–2000), Dähncke (1993), Heilmann-Clausen et al. (1998), Kränzlin (2005), Moser (1967, 1983, 1978), Ryvarden and Gilbertson (1993, 1994), Holec (2001), Wald et al. (2004), and the ecological- trophic structure were carried out after direct observations and based on literature data (Kalamees, 1979; Arnolds, 1981; Gyosheva and Vasilev, 1994; Vulchev et al., 2000). The author’s names of the fungal taxa are given by Kirk and Ansell (2004) and the plants taxa by Brummit and Powell (1992). The conservation status is indicated according to the Red List of fungi in Bulgaria (Gyosheva et al., 2006). The fungus species with conservation value are designed in the list with CV. In the trophic analysis of the larger fungi were used systems of ecological-trophic groups of Arnolds (1981). Designations of ecological-trophic groups by the abbreviated latin names of substrates: Ad – needle-debris saprotrophs, Fd – saprotrophs of fallen leaves of deciduous trees, St – litter saprotrophs, LeS – wood saprotrophs, LeP – wood parasites. Different wood substrates were studied: dead wood (branches, stumps, trunks, bark, etc.) and living trees. All specimens were deposited at the herbarium of Agricultural University – Plovdiv, Bulgaria. Specimens were collected by the author, unless otherwise stated. Maria Lacheva .

(2008) and Index fungorum (www.speciesfungorum.org: accessed 29 June 2014, and they are listed in alphabetical order. They belong to the two classes Pezizomycota (7 species) and Agaricomycota (66 species). Most species belong to the order Polyporales from the class Agaricomycetes – 20 species. Most abundant in species are the genera Mycena (4 species), and Inonotus, Phellinus, Polyporus and Stereum – 3 species in each of them. Of all species 61 were recovered from broadleaved trees, 9 from coniferous trees, and 3 from either broadleaved or coniferous trees, 2 from fallen leaves of deciduous trees, and from litter and needle-debris – one (1) species in each of them. Among them species with wider substrate specialisation were 5 species: Daedaleopsis tricolor, Laetiporus sulphureus, Pluteus cervinus, Stereum hirsutum, and S. gausapatum. A very high percentage of the lignicolous species was found on dead wood. A total of 13 species were identified as primary parasites on living trees. Somewhat less common, rare, or only found once or twice were the following: Datronia mollis, Polyporus arcularius, Scutellinia scutellata, and Volvariella bombycina. Particularly interesting were Cerrena unicolor, Clavicorona pyxidata, Peniophora quercina, and Phyllotopsis nidulans. Conversely, Hypholoma fasciculare, Psathyrella candoleana, Schizophyllum commune, Stereum hirsutum, and Trametes hirsuta was the most common species. Fifty-five (55) species, are new records for Forebalkan floristic region and are marked with an asterisk (*). Two (2) species – Clavicorona pyxidata and Phyllotopsis nidulans were included in the Red List of fungi in Bulgaria and Red Data Book of the Republic of Bulgaria (Gyosheva et al., 2006; Peev et al., 2010) with CV (Conservation
