The occurrence of marine fungi on drift wood samples collected from one sandy and one rocky beach around Yokosuka city were surveyed. Thirty-nine fungi (28 Ascomycetes and 11 mitosporic) were recorded from 90 samples. Of these, 16 fungi are new records for Japan. Twenty-nine and sixteen fungi were recorded from the sandy and the rocky beach respectively. Fungi recorded from the two beaches were significantly different with only six species common to both sites. All, but one, of the recorded ascomycetes were pyrenomycetes. Ceriosporopsis halima was very frequent fungus from both sites, while Corollospora species dominating the fungal community on the sandy beach. Other common fungi include: Arenariomyces trifurcates, Lignincola laevis and Clavatospora bulbosa. Anisostagma rotundatum and its undescribed anamorphic stage were recorded for the first time after its original description from Denmark. The anamorph-teleomorph connection was confirmed using comparative analysis of the LSU rDNA sequences. Several undescribed taxa with unfurling appendages (Halosphaeriaceae) were recorded during this study. The phylogenetic position of those undescribed taxa will be discussed.
