Intertidal marine fungi from San Juan Island and comments on temperate water species

Summary Temperate marine fungi are a distinct ecological group and differ from those found in tropical habitats, with the exception of a few cosmopolitan species. Sixty-two marine fungi were collected at San Juan Island, a temperate site, in 1994. The most frequently collected species were: Halosphaeria appendiculata, Monodictyspelagica, Halosarpheia trullifera, Ceriosporopsis halima and a new ascomycete. Eight records of Capronia ciliomaris were made, all on coniferous bark (probably Pseudosuga sp.). The fungi collected are compared with those previously reported from San Juan Island. The biogeography of marine fungi is discussed.
