Agaricus chionodermus Pilát, a species new to Bulgaria

Maria Nikolova Lacheva


The article presents the first record of Agaricus chionoderma Pilát in Bulgaria. Basidiomata of the species were found on June 2004, September 2010, and September 2011 in the Thracian Lowland floristic region. The article brings closer taxonomic profile, ecological requirements and distribution pattern of the species. Differences from similar species are discussed. It also describes macroscopic and microscopic characteristics of the discovered specimens and presents the specification of habitat the fungus concerned. The species are described and illustrated by photographs of macroscopic and microscopic features on the basis of Bulgarian specimens.
