Tapeinodasya Weber Bosse, 1904

Holotype species: Tapeinodasya bornetii Weber Bosse

Original publication and holotype designation: Weber-van Bosse, A. (1904). Note sur deux algues de l'Archipel Malaisien. Recueil des Travaux Botaniques Néerlandais 1: 96-105, 2 figs.

Description: Thallus decumbent, sympodially developed and bilaterally to dorsiventrally organized, alternately producing from every 2 or 3 cells short spine-like or longer indeterminate branches which below the apex are displaced to distichous positions. Indeterminate axes compressed and appearing winged in lower portions due to the overlap of spine-like branches on the margins. Short adventitious branches developing dorsally in the axils of some lateral branches, some of these becoming fertile. Axial cells surrounded by 4 periaxials which are quickly corticated cells by short descending rhizoidal filaments, collectively forming a thick cortex.

Fertile branches upright and radially developed. Procarps produced on short lateral branches of upright axes, consisting of a 4-celled carpogonial branch and 2 sterile groups of cells borne on the supporting cell. Carposporophytes surrounded by extensive pericarps and producing terminal carposporangia. Two tetrahedral sporangia produced in several successive segments on short lateral branches of upright axes forming short, sessile stichidia.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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