Gloeotila

Gloeotila is a genus of green algae in the class Trebouxiophyceae.

[3] Gloeotila consists of unbranched, uniseriate filaments of cells which are generally surrounded by a sheath of mucilage.

The type species, Gloeotila oscillarina, was described by Friedrich Traugott Kützing in 1843, but its original description was very poor, making it difficult to identify.

A lectotype was provided by T. E. Hazen in 1902, and the current generic concept was defined by W. Heering in 1914,[5] but some authors regard G. oscillarina as a synonym of Stigeoclonium setigerum.

As currently defined, Gloeotila contains numerous species, many of which show various affinities to other genera such as Geminella, Stichococcus, and Klebsormidium.
