19-trihydroxystemarane (13). 19-N,N-Dimethylcarbamoxy-13-hydroxystemarane (14) was not transformed by the fungus. Stemodin (1) was incubated with Whetzelinia sclerotiorum ATCC 18687 to produce 2alpha,7beta,13-trihydroxystemodane (6) and 2alpha,11beta,13-trihydroxystemodane (4). Stemodinone (7) was converted to 7beta,13-dihydroxystemodan-2-one (10). Compounds 2, 4, 9, 10, 12 and 13 have not been previously
