摘　　要：报道了褐鳞叶衣属Fuscopannaria和鳞藓衣属Psoroma的5个中国地衣型真菌新记录种:蓝缘褐鳞叶衣F.coerulescens、裂叶褐鳞叶衣F.dissecta、泰国褐鳞叶衣F.siamensis、雅褐鳞叶衣F.venusta和鳞藓衣P.hypnorum。此二属的区别在于褐鳞叶衣属地衣体无下皮层,子实层半淀粉质,光合共生物为蓝细菌;而鳞藓衣属地衣体具下皮层,子实层淀粉质,光合共生物为绿藻。蓝缘褐鳞叶衣是典型的鳞叶状地衣,其疣状次生小裂片上覆有白色萜类结晶;裂叶褐鳞叶衣的鳞片深裂,边缘上仰,具白边;泰国褐鳞叶衣具周缘裂片,次生小裂片扁平小叶状或指状;雅褐鳞叶衣的鳞片向末端繁复分支,边缘具裂芽。鳞藓衣的主要特征为地衣体具衣瘿,孢子外壁具有疣状突起。文中提供了中国新记录种的图片,并给出了此二属地衣型真菌的中国物种检索表。Five species belonging to the lichen genera Fuscopannaria and Psoroma are reported as new to China,viz.Fuscopannaria coerulescens,F.dissecta,F.siamensis,F.venusta and Psoroma hypnorum.Fuscopannaria differs from Psoroma with an ecorticated lower surface,a hemiamyloid hymenium and a cyanobacterial photobiont;whereas Psoroma has a corticated lower surface,an amyloid hymenium and a green algal photobiont.Fuscopannaria coerulescens is a typical squamulose lichen with verrucose accessory lobules covered by white terpenoid crystals.F.dissecta is characterized by its deeply dissected squamules with ascending white margins.F.siamensis is characterized by the presence of peripheral lobes and flattened or digitiform accessory lobules.F.venusta is characterized by the repeatedly branched squamules with marginal isidia.P.hypnorum is characterized by having cephalodia and warted epispores.The key to the known species of Fuscopannaria and Psoroma in China,and the illustrations for the new records are provided.
