Basidiomycetes defined

Varous inhibitors of RNA-dependent DNA-polyme-rases (reverse transcriptases) have been isolated from culture filtrates of a Canadian Mniopelalum species (Basidiomycetes), e.g., M. A C27H40O9, Mr 508.61, oil, [aJi) -63° (CHCI3) (see also marasmenes). The absolute configuration of the drimane derivative was defined on the basis of lo,15-dihydroxymarasmene C15H22O4, Mr 266.34, cryst., mp. 150-154 °C, (oId +92° (CH3OH)).
