BERK. IN BULGARIA B. Assyov*, D. Y. Stoykov, S. O. Nikolova Department of Mycology, Institute of Botany, Bulgarian Academy of Sciences, Sofia, Bulgaria ABSTRACT This paper summarizes the available data of Strobilomyces strobilaceus in Bulgaria. Review of the available previous records is made and numerous new findings are reported. Totally 30 localities of the species are currently known. An UTM-grid map is appended. The fungus appeared to be widespread, but not common and observations likely support its present conservation status. Key words: Boletales, rare fungi, red-listed fungi. INTRODUCTION Strobilomyces strobilaceus is the only European member of the otherwise extraeuropean genus (1). It is widespread throughout Europe, but is seldom and is included in the National Red Lists of a number of countries (2). It is also listed on the European Red list of fungi (3). In Bulgaria S. strobilaceus is considered to be a Vulnerable species on the National Red List of fungi (4) and therefore its monitoring and comprehensive knowledge about its distribution are essential for further conservation action. This note aims to summarize the knowledge about the distribution of this rare fungal species in Bulgaria. MATERIALS AND METHODS The available data come from the existing Bulgarian mycological literature, revision of the specimens kept in the Mycological collection of the Institute of Botany, Bulgarian Academy of Sciences (SOMF) and the Herbarium of the Plovdiv University of Agriculture (SOA), as well as from unpublished personal finds of the authors. The information is presented on UTM-grid map with 10 km square. Distribution list by floristic regions (5) is added following the usual practice. Considering that it may be useful information for the municipality management, _______________________________ *Correspondence to: Boris Assyov, Institute of Botany, Bulgarian Academy of Sciences, 23 Acad.

A list of the localities and the sources of information is added for completeness. During the revision the works of (6), (7), (8), (9) and (10) have been followed. RESULTS The review of the literature reports, the revision of the herbarium specimens, together with the unpublished collections of the authors revealed 34 records of the species.
