Abstract. Fungal specimens were collected in different floristic regions of Bulgaria during 2007 and 2012. According to the results, new data about Agaricus section Minores in Bulgaria are presented. The seven Agaricus species were registered in different floristic regions of the country. As a result of field and laboratory studies, 7 taxa belonging to Agaricus section Minores were identified. Of the species identified, Agaricus luteomaculatus (Møller) Møller, A. niveolutescens Huijsman, Agaricus porphyrizon P.D. Orton, and A. purpurellus (Møller) Møller are rare for European fungus biota. All taxa are presented with brief chorological data and notes on their distribution. Macroscopic images of some of the typical and rare species are presented. A dichotomous key for the determination of members is also included.
