✦ Synopsis

Recently we proposed (1) new structures of rugulosin (I), a pigment of enicillium rugulosum Thorn and some other fungi, luteoskyrin (II) and rubroskyrin (III), the pigments of p,. islandicum Sopp. The evidence for the structural formulae was provided mostly by the NMR spectral analysis of these compounds and their derivatives.
