Taxonomic status: currently recognized as a distinct genus.

Most recent taxonomic treatment adopted: Schneider, C.W. & Wynne, M.J. (2007). A synoptic review of the classification of red algal genera a half a century after Kylin's "Die Gattungen der Rhodophyceen". Botanica Marina 50: 197-249.

Nomenclatural notes
Two species were originally included: T. pennyi and T. mertensiana; Schmitz (in Rosenvinge 1893: 815) clearly indicated "Species typica Trunerella Mertensiana (Post. et Rupr.) Schmitz." - (23 Jan 2017) - M.D. Guiry

Description: Gametophytic plants reach 60 cm in height, are erect from a discoid holdfast, and are irregularly lobed to lacerate blades. Axes are multiaxial, the medulla being broad and filamentous, surrounded by a cortex with large gland cells scattered in the outer layers. Carpogonial branches are 3(-4)celled. Cystocarps are ostiolate and deeply embedded in the fronds. Carposporophytes consist of an irregularly dissected central fusion cell surrounded by a few layers of sterile gonimoblasts bearing chains of carposporangia. Pericarps lack a filamentous internal layer. Spermatangia are unreported. Tetrasporophytes are heteromorphic to gametophytes, being in the form of small crusts (South et al. 1972).

Numbers of names and species: There are 8 species names in the database at present, as well as 2 infraspecific names. Of the species names, 3 have 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.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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