Taxonomic notes
Family placement uncertain according to Wilson et al. (2002) and Schneider & Wynne (2007: 199); J.A. West suggested Stylonemataceae (Feb. 2019). - (4 Oct 2010) - M.D. Guiry

Description: Thalli microscopic, forming erect, dichotomously branched pseudofilaments. Cells surrounded by a thick mucilaginous sheath. Pseudofilaments uniseriate initially, becoming pleuriseriate except at the distal end and the basal region. Each cell containing several parietal, disk-shaped chloroplasts lacking pyrenoids. Contains B-Type II phycoerythrin. Pit plugs absent. Growth intercalary or diffuse, except in very early stages of development following spore germination when growth may be apical. Attached to the substratum by basal cells lacking rhizoids. Asexual reproduction by archeospores; entire vegetative cells transformed into archeosporangia with each releasing a single, wall-less archeospore. Sexual reproduction unknown. Growing in the subtidal zone typically epiphytic on other algae, but may be saxicolous. Distributed from Prince William Sound, Alaska to Carmel Bay, California. Also reported from the N. Atlantic and the Mediterranean.

Numbers of names and species: There are 2 species names in the database at present, of which 2 have been flagged as accepted taxonomically on the basis of the listed literature under the species name. In some instances, opinions on taxonomic validity differ from author to author and users are encouraged to form their own opinion. AlgaeBase is a work in progress and should not be regarded as a definitive source only as a guide to the literature..

Names: ('C' indicates a name that is accepted taxonomically; 'S' a homotypic or heterotypic synonym; 'U' indicates a name of uncertain taxonomic status, but which has been subjected to some verification nomenclaturally; 'P' indicates a preliminary AlgaeBase entry that has not been subjected to any kind of verification.

Verification of data
Users are responsible for verifying the accuracy of information before use, as noted on the website Content page.

Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
