MORPHOLOGY AND TAXONOMY OF SOME SOIL ALGAE (SUBFAMILY SCOTIELLOCYSTOIDEAE, CHLORELLACEAE) FROM THE CULTURE COLLECTION OF ALGAE AT INNSBRUCK(ASIB, AUSTRIA)

Members of the subfamily Scotiellocystoideae FOTT 1976 are often found in terrestrial habitats and characterized by their sculptured cell wa ll with meridional ribs. Six isolates of the genera Scotiellopsis, Coe lastrella and Graesiella from the culture collection of algae at the u niversity of Innsbruck (Austria) have been investigated with light- an d electron microscope and new or additional observations on morphology , cytology and reproduction are dealt with. The taxonomic position of each strain is also discussed.
