Lambertellin, a metabolite of Ciboriagordonii Funk

Abstract

Lambertellin, 9-hydroxy-3-methyl-2H-naphtho[2,3-b]pyran-2,5,10-trione, previously identified from species of Lambertella and Pseudospiropes, has been isolated from the discomycete Ciboriagordonii Funk, identified on needles of the western hemlock Tsugaheterophylla. Spectral data and a crystal structure are given for lambertellin, confirming the structure in the literature.
