Illudanes. Sesquiterpenoids with the illudane skeleton occur in basidiomycetes and ferns ( pterosins). They are derived biosynthetically from humulene. Numerous derivatives of I. have been isolated from cultures of Omphalotus illudens (=Clitocybe illudens) and Lampteromyces japonicus, e.g., the toxic illudin M C15H20O3, Mr 248.32, cryst., mp. 130-131 °C, [ajp -126° (C2H5OH) and illudin S C15H20O4, Mr 264.32,... 

C22H28N40,o, Mr 508.49. The Japanese moon night mushroom Lampteromyces japonicus (Tsukiyo-take, Basidiomycetes) shows a green glowing on the underside of its cap (emission) 524 nm]. L. is responsible for this bioluminescence, and is isolated from the fruit bodies of the freshly collected toadstool. The strongly fluorescent compound is very unstable and decomposes rapidly in aqueous solution under formation of riboflavin(e). 

The D-mannan (22) isolated from Lampteromyces japonicus resembles that from 5. cerevisiae except for the absence of (1 3)-linkages. A closer structural resemblance exists with the D-mannans of Saccharomyces rouxiU Trichosporon aculeatum, and Candida albicans. 

Most Basidiomycetes synthesize activity and are therefore able to hydrolyse sodium carboxymethylcellulose. Only a few Basidiomycetes e.g, Irpex lacteus, Trametes sanguinea, Fomitopsis cytisina, Lampteromyces japonicus, Pholiota adiposa, and Stropharia cubensis) produce an enzyme (Ca activity) able to hydrolyse filter paper the enzyme appears to be inducible. 

The toxic mushroom Lampteromyces japonicus contains a highly dextrorotatory polysaccharide that is composed of residues of o-glucose, D-mannose, and D-galactose the polysaccharide showed anti-tumour activity towards implanted sarcoma 180 in mice. Structural studies indicated that the purified polysaccharide contains mainly (1 -> 6)- and (1 -> 2)-linked D-mannopyranosyl, (1 -> 3)-linked D-glucopyranosyl, and (1 -> 6)-linked o-galactopyranosyl residues, with branching at 0-6 of some of the D-glucopyranosyl residues. ... 

Illudin-S has also been isolated from the moon-night-mushroom (Lampteromyces japonicus), a poisonous bioluminescent mushroom growing in Japan, K. Nakanishi, M. Ohashi, M. Tada and Y. Yamada, Tetrahedron, 21, 1231 (1965).
