Dicranemaceae (Kraft 1977: 239). - (22 Jul 2009) - Wendy Guiry
Description: Plants are generally prostrate and imbricate, the clumps reaching 15 cm in diameter. Thalli are composed of flattened, subdichotomous fronds of irregular widths anchored at scattered points by stout, terete haptera. Axes are with or without marginal proliferations. The filamentous medulla is generally less than 1/5 the diameter of the axes and is surrounded by a deep pseudoparenchymatous cortex. Gland cells situated at the bases of deciduous hairs are commonly scattered in the outer cortex. Cystocarps are single or clustered distally and are composed of an outwardly oriented placenta and chains of 4-6 carposporangia developing into a chamber formed by breakdown of gametophytic tissue. Tetrasporangia occur in subapical nemathecia.

Numbers of names and species: There is only one species or infraspecific name in the database at present, which has 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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
