<jats:title>Abstract</jats:title> <jats:p>Chemical screening of culture medium from the soil fungus Stachybotrys sp. resulted in the isolation of the three new phenylspirodrimanes MBJ-0030 (1), MBJ-0031 (2) and MBJ-0032 (3). Their structures were determined by detailed analysis of spectroscopic data. The absolute configurations of 1–3 were determined by modified Mosher’s and Marfey’s methods. In addition, cytotoxic and antimicrobial evaluations of the compounds were conducted.
