    Four new species of Emericella, E. discophora, E. E. olivicola. and E. stella-maris, are proposed. Their new taxonomic status was determined applying a polyphasic taxonomic approach using phenotypic (morphology and extrolite profiles) and molecular (sequences of ITS, P-tubulin and calmodulin genes) characters. Ascospores of E. stella-maris arid E. olivicola have star-shape equatorial crests, those of E. filifera form long appendages that emerge radially from narrow stellate crests and those of E. discophora produce wide arid entire, nonstellate equatorial crests. E. stella-maris originated from leaf fitter in Tunisia and E. filifera, from raisins in Argentina, arid both of them also were found in hypersaline water of a saltern in Slovenia. E. olivicola was isolated from olives in Italy and E. discophora, from soil in Spain. All listed species possess distinct extrolite profiles: E. stella-maris produced arugosin E, shamixanthone arid the yet unelucidated metabolites glia 1-3; E. filifera produced shatnixanthone and varitriols; E. discophora. produced sterigmatocystin and versicolorins; E. ohvicola produced numerous extrolites such as arugosin E, siderin, shamixanthone, sterigmatocystin, terrein, varitriols arid aflatoxin B-1, of which the latter was detected only in one of the two strains.
