细鞘丝藻属（学名：Leptolyngbya）也称瘦鞘丝藻属，为细鞘丝藻科的一属蓝藻。此属的模式种为鲍氏细鞘丝藻（Leptolyngbya boryana）[1]。

分类

细鞘丝藻属于1988年建立，最初归类于颤藻目[1]。2005年被归入假鱼腥藻目（Synechococcales）假鱼腥藻科（Pseudanabaenaceae）[2]。2007年依据细鞘丝藻的类囊体排列与发育模式，将其重新归类到聚球藻目（Chroococcales）假鱼腥藻科[3]。

2014年将细鞘丝藻属从假鱼腥藻科分离出来，成立了独立的细鞘丝藻科（Leptolyngbyaceae），该科包括细鞘丝藻属等多个属[4]。

形态特征

细鞘丝藻属的藻丝极为细小，宽度一般在1-2 µm，并被单独的鞘包裹。藻丝通常附着于基质上，末端通常不呈渐尖状，很少具有假分枝[5]。
