Abstract: Abstract:Remispora was established for R. maritima, a fungus with globose/subglobose, lightly colored and coriaceous ascomata; deliquescing asci; ellipsoidal ascospores; and bipolar, pleomorphic ascospore appendages. Seven species currently are included in Remispora: R. crispa, R. galerita, R. maritima, R. minuta, R. pilleata, R. quadriremis and R. stellata. Variations on ascospore appendages can be observed in Remispora. In general the appendage is exosporic in nature and comprises an amorphous, electron-transparent matrix and a fibrous, electron-dense component. An eighth Remispora species, R. spitsbergenensis sp. nov., is described here, discovered from washed-up wood collected at the shore of Long-yearbyen, Svalbard, Norway. Ascospore appendages of R. spitsbergenensis appear as fibrous strands and amorphic material under the scanning electron microscope, which are characteristic of a Remispora species. Remispora spitsbergenensis resembles R. quadriremis and R. stellata because all possess four or more ascospore appendages at one end. Remispora spitsbergenensis possesses consistently four polar appendages at each end in contrast to six in R. stellata. Also ascospore appendages of R. spitsbergenensis are ribbon-like, compared with the obclavate, curved and attenuate appendages in R. quadriremis and R. stellata. A key for the identification of the eight Remispora species is provided.
