Penicillium wortmanni

Penicillium verruculosum, and Penicillium wortmanni The chemical constituents of the acidic polymer from P. aculeatum var. apicula-tum are similar to those of luteic acid, but it differs in that it does not form an insoluble copper complex and has a higher viscosity. The molecular weight of the derived, neutral polymer is, by sedimentation, 1.6 X 10 (10,000 units), corresponding to 2.0 X 10 for the parent acid. ... 

The parent pigment of this group, flavomannin (343), the A type atropisomer of which has been isolated from Cortinarius odoratus, was first described as a metabolite of the mould Penicillium wortmanni (53).
