Japanese species of Hypomyces and their anamorphs IV

Abstract

Five boleticolous Hypomyces species and their Sepedonium anamorphs collected in Japan are described and discussed: H. melanocarpus, H. transformans, H. chlorinigenus, H. chrysospermus and H. microspermus. The former two species are newly reported to Japan. Tylopilus valens, which is endemic to Japan, was reported as a new host of H. melanocarpus. Differences in two similar species, H. chrysospermus and H. microspermus, are discussed.
