Amone A, Cardillo R, Di Modugno V, Nasini G (1988) Secondary Mould Metabolites. XXII. Isolation and Structure Elucidation of Melledonals D and E and Melleolides E-H, Novel Sesquiterpenoid Aryl Esters from Clitocybe elegans and Armillaria mellea. Gazz Chim Ital 118 517... 

Over 30 sesquiterpene aryl esters have been isolated from Armillaria spp. of these, eight are esterified with chlorinated orsellinate. The honey mushroom, A. mellea, produces 70 mg of the chlorinated compound armillaridin (122) per kg dry mycelium [148], while liquid cultures of A. ostoyae contain the chlorinated compounds, melledonal C (123) (50 mg/1) and melleolide D (35 mg/1) (124) [149]. Clitocybe elegans is the only other genus for which chlorinated sesquiterpene aryl esters have been reported [150], including melledonal D (125), which has not yet been detected in Armillaria spp. The pathogenic basidiomycete, Armillaria causes root disease in both coniferous and deciduous trees.
