    Samenvatting

    Four new species of Emericella, E. discophora, E. filifera, 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, beta-tubulin and calmodulin genes) characters. Ascospores of E. stella-maris and 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 and entire, nonstellate equatorial crests. E. stella-maris originated from leaf litter in Tunisia and E. filifera from raisins in Argentina, and 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 and the yet unelucidated metabolites glia 1-3; E. filifera produced shamixanthone and varitriols; E. discophora produced sterigmatocystin and versicolorins; E. olivicola produced numerous extrolites such as arugosin E, siderin, shamixanthone, sterigmatocystin, terrein, varitriols and aflatoxin B1, of which the latter was detected only in one of the two strains.
