Description: Thallose - thallus composed of free, densely irregularly coiled, creeping filaments. Sheaths thin, firm, colorless, homogeneous. Trichomes always uniseriate, with cylindrical cells, not or slightly constricted at crosswalls, commonly irregularly laterally true-branched; branching of T-type; branches more or less short, 1-2-few-celled, terminated by apical, unipored heterocytes or long, continually tapering to the hair-like ends. Cells more or less isodiametric or longer than wide (especially in ends of branches), blue-green or pinkish. Heterocytes terminal at branches or lateral (laterally attached to trichomal cells), rarely intercalary, usually solitary, rarely in pairs. Akinetes missing. Cells divide crosswise and lengthwise before branching. Reproduction by hormogonia. Marine; creeping epilithic on calcareous stones and on the surface of shells of molluscs, distributed over the European, South African and American coasts of the temperate and subtropical zone. Data from freshwaters (M. testarum var. aquae-dulcis from rivers in Russia) needs revision. Revised description (Ramirez-Reinat & Garcia-Pichel 2012: 747).

Contributors
Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in CD format. These AlgaeBase descriptions are now being continually updated, and each current contributor is identified above. The PSA and AlgaeBase warmly acknowledge the generosity of all past and present contributors and particularly the work of Dr Parker.

Descriptions of chrysophyte genera were subsequently published in J. Kristiansen & H.R. Preisig (eds.). 2001. Encyclopedia of Chrysophyte Genera. Bibliotheca Phycologica 110: 1-260.
