Assyov*, D. Y. Stoykov, M. Gyosheva Department of Plant and Fungal Diversity and Resources, Institute of Biodiversity and Ecosystem Research, Bulgarian Academy of Sciences, Sofia, Bulgaria ABSTRACT The paper reports 23 rare and noteworthy Bulgarian larger fungi including the confirmation of the presence of Paxillus rubicundulus in the country and the second records of Cantharellus pallens, Crinipellis mauretanica, Ditiola peziziformis, Geopora arenicola, Laccaria proxima, Marasmius collinus and Pterula multifida. Brief descriptions are provided for Cantharellus pallens, Ditiola peziziformis, Geopora arenicola, Gymnopus quercophilus, Marasmius collinus, and Paxillus rubicundulus based upon the Bulgarian specimens. Geopora arenicola, Trichoglossum hirsutum var. hirsutum, Cantharellus amethysteus, C. pallens, Laccaria proxima and Paxillus rubicundulus are illustrated. In addition, new collections of some threatened, rare and less known species are also included. Key words: ascomycetes, basidiomycetes, Bulgarian mycota, fungal conservation, larger fungi INTRODUCTION the determination are listed under every Recording of fungi is an important task which particular taxon as ‘Reference literature’. serves different scientific and practical purposes.
