Macroscopic and microscopic features of the fresh samples were photographed and a diagnostic key of the genus Barssia was built considering characteristics of known species. Key words: Hypogeous fungi, phylogeny, taxonomy 1. Introduction The genus Barssia Gilkey, which belongs to the family Helvellaceae, is currently represented by only five species in the world. All species of the genus Barssia were found at a latitude of 30° in the northern hemisphere until today (Figure 1). The first species of Barssia was collected by Barss in Oregon, USA, under Rhamnus purshiana DC. and named as Barssia oregonensis Gilkey (Gilkey, 1925). This was followed by B. peyronelii (Mattir.) Agnello & Kaounas (described as Stephensia peyronelii Mattir.) found under Larix decidua Mill. in Piedmont, Italy (Mattirolo, 1936; Agnello and Kaounas, 2017) and B. yezomontana (Kobayasi) Trappe (originally named as Phymatomyces yezo-montanus Kobayasi) found under Abies mayriana Miyabe & Kudô and Picea jezoensis Carrière in Yezo, Japan (Kobayasi, 1937; Gilkey, 1961). Later, B. maroccana , Manjón, Carlavilla & .
