Original publication and holotype designation: Kraft, G.T. (1977). Studies of marine algae in the lesser-known families of the Gigartinales (Rhodophyta). II. The Dicranemaceae. Australian Journal of Botany 25: 219-267, 20 figs.
Request PDFDescription: 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.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera,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.
