Many other edible mushrooms produce oct-l-en-3-ol and other Cg compounds together with different metabolites that give them their characteristic taste. The ratio of the Cg compounds may vary. 3-Methylbutanal, 3-methylbu-tanol, benzaldehyde and phenylacetaldehyde, together with 1- and 2-phenyl-ethanol, have been detected in Boletus edulis. 

Singer (1963) reported that mycelium implanted in beds of horse manure/straw compost for 7-14 months produced mushrooms directly after the appearance of rhizomorphs. J. Garbaye etal. (1 979) published data indicating that the supplementation of natural patches with a NPKCa mineral fertilization induced large fruitings of L nuda as well as Boletus edulis and Lepiota rachodes. two unrelated species of culinary distinction. 

F. Kutscher (3), who gave it the name hercynine, and it was subsequently found in Boletus edulis Bull, by C. Reuter (4). Ergothioneine (V) was isolated from ergot by C. Tanret (5), and it was extensively investigated by G. Barger and A. J. Ewins (6). It has also been isolated from blood (7, 8). 

In the Ames test for mutagenicity in SalmoneUa typhimurium, mutagenic activity of shiitake was observed without metabolic activation in Salmonella tester strains sensitive to base-pair substitution mutagens. Mutagenicity of other commonly consumed edible mushrooms, including Agaricus bisporus and Boletus edulis, was observed (Von Wright et al. 1982).
