Pulcherricium caeruleum

The leuco peracetate of thelephoric acid (85) has been isolated from Boletopsis leucomelaena [69], The leuco permethyl ether of thelephoric acid (86) was obtained in minute amounts from mycelial mat of Pulcherricium caeruleum (Corticium caeruleum), a basidiomycete characterized by an indigo blue colour of its hymenial surface, and its... [Pg.284]

Recently, the leuco-peracetate (54) of thelephoric acid has been isolated from sporophores of Boletopsis leucomelaena (386). The leuco-permethyl ether (67) of thelephoric acid occurs in minute amounts in the indigo blue coloured mycelial mats of Pulcherricium caeruleum ( = Corticium caeruleum) and its structure has been established by an X-ray crystal analysis (581, 711). The chemical nature of the blue pigment from this organism is a matter of dispute. Briggs et al. (135) obtained blue solutions (A, ax = extraction of the mycelium... [Pg.31]
