摘　　要：从青海省祁连山脉首次报道了奥地利真藓(Bryum austriacum Kockinger, Holyoak&Suanjak)在中国的分布。该种的主要识别特征为:植株纤弱,黄绿色至浅褐色;叶卵状披针形,强烈内凹,覆瓦状排列;叶细胞大,薄壁,疏松排列;大量深棕红色的卵状芽胞在叶腋处单个着生;叶原基小,半透明。该种可能起源于中亚,是高山草甸上腐殖质和富营养化土壤的先锋植物。编制了中国真藓属中有叶腋生球形芽胞物种的分种检索表。标本存放于华东师范大学植物标本馆(HSNU)和焦作师专植物标本馆(JZNC)。Bryum austriacum Kockinger, Holyoak & Suanjak is reported new to China from the Qilian Mountains in Qinghai Province. The species is characterized by delicate, pale-coloured plants;imbricate and strongly concave leaves with very large, loose, and thin-walled cells;abundant dark red-brown ovoid bulbils with 3-5(7) small and translucence leaf primordia, occurring singly in each leaf axils. The newly recorded species possibly originated from Central Asia. It appears to be a pioneer mainly on humus-and base-rich soil in alpine meadows. An identification key for bulbiferous species of Bryum in China is provided. The voucher specimen are deposited in the Herbarium of East China Normal University(HSNU) and the Herbarium of Jiaozuo Normal College(JZNC).
