New data about macrofungal diversity in Bulgaria.

Five macrofungi are reported for the first time from Bulgaria. One species (Podophacidium xanthomelum) belongs to Ascomycota and four species (Arrhenia obatra, A. sphagnicola, Marasmius curreyi, and Thelephora penicillata) belong to Basidiomycota. Podophacidium (Helotiales) is new to the country at generic level. Descriptions and illustrations of the studied specimens are provided. New localities of about twelve macrofungi are also reported. Five of them (Arrhenia lobata, A. onisca, A. spathulata, Guepinia helvelloides and Hericium flagellum) are of high conservation value. [ABSTRACT FROM AUTHOR]
