II. Recent data of study M. Lacheva* Department of Botany and Agrometeorology, Faculty of Agronomy, Agricultural University Plovdiv,12 Mendeleev, 4000 Plovdiv, Bulgaria Abstract. The species composition, distribution, ecological-trophic structure and conservation value of macromycetes in Maglenishki Rid (Eastern Rhodopes Mts) is studied. 102 macromycetous species were registered. The predominant part of macromycetes belongs to the class Agaricomycetes (99 species), another part belongs to the Ascomycetes (2 species) and Myxomycetes (1 species). Fifteen macromycetous species are rare for the country, eleven of them of high conservation value are included in the Red List of endangered macromycetes in Bulgaria. All taxa are presented with brief chorological data and notes on their distribution in the region.
