Neostromatella M.J., G. & R. , 2014
Holotype species: Neostromatella monostromatica M.J.Wynne, G.Furnari & R.Nielsen
Original publication and holotype designation: Wynne, M.J. & Furnari, G. (2014). A census of J.P.L. [sic] Dangeard's invalid taxa with proposals to resolve the nomenclatural problems of some of them. Nova Hedwigia 98(3-4): 515-517.
Taxonomic status: currently recognized as a distinct genus.
Gender: This genus name is currently treated as feminine.
According to Wynne & Furnari (2014: 516-7), the "... name Stromatella was first proposed by Kornmann & Sahling (1983), with two species included in it (S. monostromatica and S. papillosa), with neither designated the type species. In a footnote, Kornmann & Sahling (1985) designated S. monostromatica to be the Type. Silva et al. (1996) thought that the generic name had been validated by Kornmann & Sahling%u2019s (1985) designation of a type species. However, because that species was based on Ulvella monostromatica (Dangeard 1965a), an invalid name, according to Art. 10.3 of the Melbourne Code (McNeill et al. 2012), the generic name is also invalid. That makes legitimate the name Stromatella applied for a genus of lichen (Henssen 1989)." The legitimisation of the lichen name precluded the validation of Stromatella Kornmann & Sahling necessitating the introduction of a new genus name. - (16 Apr 2014) - M.D. Guiry
Description: Thallus microscopic, prostrate, monostromatic, filamentous growth outward, with the inner region becoming pseudoparenchymatous and the distal filaments not consolidated but loosely growing at the circumference, so with an irregular thallus margin. Thalli typically growing epiphytically and firmly on other algae. Cells with a single chloroplast with a single pyrenoid. Reproduction by means of ordinary vegetative cells in the center of the thallus forming sporangia and cleaving typically into 8 zoospores. Sporangia first appearing in the center of the thallus and gradually being developed toward the periphery. The settled zoospores germinate by enlargement. After the first cell division the germlings often have one rounded, nearly globular cell with a diameter slightly larger than the other cell. Following the development, the young plants often show a bilateral symmetry.

Numbers of names and species: There is only one species or infraspecific name in the database at present, which has 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.

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.
