杉木上舟皮盘菌属一新种

本文报道在安徽省岳西县发现的舟皮盘菌属(Ploioderma Darker)一新种,即毁坏舟皮盘菌(P.destruens Y.R.Lin et Hou P.nov.)。该种以子囊具长柄,侧丝顶端显著膨大以及产生分生孢子果和线纹等特征,区别于近似种P.handelii(Petrak)Y.R.Lin et Hou。在发生地,此菌引起严重的杉木Cunninghamia lanceolata(Lamb.)Hook.]梢枯病。

A NEW SPECIES OF PLOIODERMA (RHYTISMATACEAE)ON CHINESE FIR

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.].
