*3.3.1.1. Diversity of cythane diterpenes*

A number of other biologically significant cyathane diterpenoids have been isolated from the fruiting bodies of mushroom *Sarcodon scabrosus* [65–67], *Sarcodon glaucopus* [68, 69], and *Sarcodon cyrneus* [70, 71] and the culture of fungi *C. helenae* [72], *C. africanus* [73], *C. earlei*
