Abstract

is a novel species from Greenland that grows exceptionally slowly at 25 °C and has an optimum temperature for growth of 17–18 °C. The novel species is more psychrotolerant than any other species described to date. Isolates of this novel species produce a range of secondary metabolites with a high chemical diversity, represented by kojic acid, penicillic acid, griseofulvin, pseurotin, chrysogine, tryptoquivalins and cycloaspeptide. , another novel psychrotolerant species from the Rocky Mountains, Wyoming, USA, produces asperfuran, kojic acid and cycloaspeptide. Originally reported from an unidentified species isolated from Nepal, cycloaspeptide A is reported here for the first time from the two novel species and two known psychrotolerant species with high chemical diversity, and . All species, except , produce a combination of cycloaspeptide and griseofulvin. However, (3/5 strains) produced the precursor to griseofulvin, norlichexanthone. The type strain of sp. nov. is DAOM 234087 (=IBT 21984=IBT 24411=CBS 102888) and the type strain of sp. nov. is DAOM 234091 (=IBT 16537=IBT 24431).
