Thirty eight species from eighteen genera of ascomycetous and anamorphic fungi are reported for the first time from Mt. Strandzha in Turkey.

Information about the first finding in Bulgaria and the Balkan Peninsula of Boletus roseoalbidus (= Xerocomus roseoalbidus) is presented. A description and illustrations are provided upon the Bulgarian collections. Cytospora sacculus on Ailanthus altissima is a new record for Bulgaria. Four ascomycetes, Hyponectria buxi, Plagiosphaera immersa, Pleuroceras pleurostylum, Pseudovalsa umbonata, are reported for the first time from Bulgaria.

One genus (Ditopellina) and three species (Ditopellina saccardiana, Gnomonia nantensis, and G. rosae) of Diaporthales are reported as new to Bulgaria. Nine species (Apiognomonia errabunda, Apioplagiostoma carpinicolum, Apioporthella vepris, Ditopellina saccardiana, Gnomonia comari, G. nervisequa, G. rosae, Hypospilina pustula, and Plagiostoma arnastadtiense) are established on new substrata, and 21 species are recorded from new Bulgarian localities.

The occurrence of Phomopsis diachenii on caraway (Carum carvi) was established in 2001. This is the first report of P. diachenii in Bulgaria. The pathogen produced black pycnidia and two types of conidia (alpha- and beta-conidia) on infected plant tissues as well as on nutrient media. Another Phomopsis species was found on the same host plant in 2003. It produced mainly alpha-conidia. In addition, mature perithecia assigned to Diaporthe angelicae were observed on stem fragments taken from annual caraway (C. carvi var. annuum) in 2003. Phomopsis spp. were isolated from wild growing caraway and Heracleum plants collected in the region of Rila monastery, too. All fungi mentioned were studied on the host plant and in agar culture.
