Leiomenia Huisman & G.W.Saunders, 2017

Holotype species: Leiomenia lacunata Huisman & G.W.Saunders

Original publication and holotype designation: Saunders, G.W., Huisman, J.M., Vergés, A., Kraft, G.T. & Le Gall, L. (2017). Phylogenetic analyses support recognition of ten new genera, ten new species and 16 new combinations in the family Kallymeniaceae (Gigartinales, Rhodophyta). Cryptogamie Algologie 38(2): 79-132, 126 figs.

Description: Thallus with solid or obligately perforate membranous blades, the medulla primarily of sparse filaments and lightly staining stellate cells with irregularly radiating arms. Spermatangia cut off from outer cortical cells. Supporting cell systems mono- or polycarpogonial, bearing up to 4 carpogonial branches and 3–5 subsidiary cells. Fusion cell prominent, incorporating the supporting and subsidiary cells, producing numerous connecting filaments. Auxiliary cell systems with an auxiliary cell and 3–6 (–10) spherical subsidiary cells. Following fusion with a connecting filament, the auxiliary cell produces numerous gonimoblast filaments ultimately cutting off carposporangia. Cystocarps within the medulla, consisting of a dense mass of intermixed filaments and spherical to ovoid carposporangia. Tetrasporangia scattered in the outer cortex, cruciately divided.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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