細鞘絲藻屬（學名：Leptolyngbya）也稱瘦鞘絲藻屬，為細鞘絲藻科的一屬藍藻。此屬的模式種為鮑氏細鞘絲藻（Leptolyngbya boryana）[1]。
分類
[編輯]細鞘絲藻屬於1988年建立，最初歸類於顫藻目[1]。2005年被歸入假魚腥藻目（Synechococcales）假魚腥藻科（Pseudanabaenaceae）[2]。2007年依據細鞘絲藻的類囊體排列與發育模式，將其重新歸類到聚球藻目（Chroococcales）假魚腥藻科[3]。
2014年將細鞘絲藻屬從假魚腥藻科分離出來，成立了獨立的細鞘絲藻科（Leptolyngbyaceae），該科包括細鞘絲藻屬等多個屬[4]。
形態特徵
[編輯]細鞘絲藻屬的藻絲極為細小，寬度一般在1-2 µm，並被單獨的鞘包裹。藻絲通常附著於基質上，末端通常不呈漸尖狀，很少具有假分枝[5]。
