Holotype species: Arnoldiella conchophila V.V.Miller

Original publication and holotype designation: Miller, V. (1928). Arnoldiella, eine neue Cladophoraceaeengattung. Planta 6: 1-21.

Description: Thallus differentiated into a prostrate layer consisting of coalescing filaments and a compact system of rigid upright filaments. Cells of the prostrate layer with one to few nuclei, cells of the erect filaments multinucleate. Erect filaments can be densely or sparsely branched. Branches more numerous in apical parts of the thallus. Primary, secondary and tertiary branching can be present in erect filaments. Branches inserted subterminally or cut off by an almost horizontal cross wall resulting in a pseudodichotomy. Cells gradually becoming shorter and wider from base to apex. Apical cells rounded or pointed. Thick cell walls, at least in basal parts. Terminal zoosporangia, sometimes formed in chains.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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