The exomethylene furan alcohol 2, which is formed when fatty acid esters of velutinal 1 isolated from Lactarius species are degraded on silicagel, correlates the absolute configuration of isovelleral 5a with that of other sesquiterpenes isolated from Lactarius sp.

Velutinal esters of lactarius vellereus and L. Necator. The preparation of free velutinal.
In addition to already known sesquiterpene aldehydes, the lactaranes piperdial 1 and piperalol 2 were isolated from extracts of Lactarius piperatus, L. torminosus and Russula queletii (larger fungi).
