A NEW SPECIES OF PLOIODERMA (RHYTISMATACEAE)ON CHINESE FIR
杉木上舟皮盘菌属一新种

A new species of the genus Ploioderma Darker, P. destruens Y. R. Lin et Hou, is described and illustrated based on a collection from Yuexi County, Anhui Province. The taxon can be distinguished from its affinity, P. handelii (Pe-trak) Y. R. Lin et Hou, by its much longer-stalked asci, the shape of its paraph-yses, which are obviously swollen at the apex, and the presence of conidiomata and zone lines. The fungus causes a serious dieback of Chinese fir Cunninghamia la-nceolata (Lamb.) Hook.].
