A new species of Penicillium, P. scabrosum

A new species of Penicillium, P. scabrosum, was found repeatedly in soil samples from temperate regions of the world, especially northern Europe and Canada. It occurs in high frequencies in wheat and barley field soils together with P. janczewskii Zaleski. The species has also been found on fleshy fungi and in foods, particularly as a spoilage organism in food containing lipid and cereal-containing feedstuff. It produces many unknown strongly coloured secondary metabolites. Known mycotoxins from the species include fumagillin, viridicatin, and viridicatol.
