Three new unusual sesquiterpenes (1–3) were isolated from the tropical rainforest basidiomycete, Marasmiellus troyanus and their structureelucidation was achieved by NMR spectroscopy, single-crystal X-ray structural analysis and a modified Mosher’s ester method to determine the absolute stereochemistry of compound 1. These unusual metabolites are probably derived from the caryophyllane class of sesquiterpenes
