中国新疆天山中东部新记录地衣种类(英文)

文中对采自乌鲁木齐市郊区和南山小渠子多个生境中的大量标本进行了外部形态与内部解剖特征观察,并对少数标本采用了显色反应法(CT)、显微化学结晶法(MCT)及薄层色谱法(TLC)等方法进行了物种鉴定。结果表明:该地区分布的地衣种类有100多种,其中包括1个中国新记录种———副茶渍属(Lecania tonin-ioides),2个新疆新记录种———美国大孢蜈蚣衣(Physconia americana)和细裂岛衣(Cetraria delisei)。副茶渍属的主要特征是鳞状地衣体边缘粉色,子囊长棍棒状,常生长在地面上;美国大孢蜈蚣衣的主要特征是小裂片旺生在子囊盘边缘和地衣体成熟的部分;细裂岛衣的主要特征是子囊棍棒状,髓层C+粉红色,含三苔色酸。文中对这些种类进行了简略描述。

New Records of Tianshan Lichens from Mt. Xinjiang, Middle East of China

Based on large-scale investigation and sampling in urban district of Urumqi and Xiaoquzi,more than 100 lichen species were found and identified by using lightmicroscope and scanning electron microscope.Some species identified by using colour test(CT),micricrystal test(MCT) and thin layer chromatography(TLC).As a result,one species ofthe lichengenusLecanianewto China and two species of lichen genusPhysconiaandCetrarianew to Xinjiang were identified.InLecania toninioidestypical form,it is easily recognized by its squamulose thalluswith pale edges,its long ascospores,and its usual occurrence on soil.Physconia americanais characterized by its developing tiny lobules on the apothecial margins and old parts of thallus.Cetraria deliseiis characterized by its ova-l clavate Asci,Medulla C+ pink,contain gyrophoric acid.These species were briefly described and reported on this paper.
