Two newditerpenic glycosides, virescenosides M (1) and N (2), have been isolatedfrom a marine strain of Acremoniumstriatisporum KMM 4401 associated with the holothurian Eupentacta fraudatrix. Their structures were determined on the basis of MS and NMR data as beta-D-altropyranosido-19-7-oxo-isopimara-8,15-diene-2alp ha, 3beta-diol (1) and beta-D-altropyranosido-19-isopimara-7, 15-diene-2alpha,3beta
