The Mesostigmatophyceae are a class of basal green algae found in freshwater. [3] [4] [5] In a narrow circumscription, the class contains a single genus, Mesostigma . [6] AlgaeBase then places the order within its circumscription of Charophyta. [1] A clade containing Chlorokybus and Spirotaenia may either be added, [7] [8] [9] [10] [11] [12] or treated as a sister, with Chlorokybus placed in a separate class, Chlorokybophyceae. [13] When broadly circumscribed, Mesostigmatophyceae may be placed as sister to all other green algae, or as sister to all Streptophyta. [14] [15] [16]
