Ascospore appendages of marine ascomycetes: An evaluation of appendages as taxonomic criteria

Abstract

Ascospore appendages of 18 marine Ascomycetes, belonging to the genera Amylocarpus, Carbosphaerella, Corollospora, Eiona, Emericellopsis, Haligena, Halosphaeria, Lulworthia, Remispora and Torpedospora, were examined with the scanning electron microscope. A number of basic types of spore appendage development are recognised. The significance of these observations to the taxonomy of marine Ascomycetes, and especially the Halosphaeriaceae, is discussed. Remispora is considered a valid genus and not a synonym of Halosphaeria. Both Corollospora and Halosphaeria are considered to be an assemblage of disparate species. The establishment of new genera is considered premature until material of other species has been re-examined. The ontogeny and structure of spore appendages are considered useful taxonomic criteria at the specific and generic level.
