[Taxacom] Botanical (algal) families ending in -ataceae

This is a common problem also for zoological names, "stemming" from people using the wrong stem for the type genus, e.g., Skeletonem- instead of Skeletonemat-
I don't know the botanical Code well enough to know how they handle it ...

Dear Taxacomers,

I am trying to reconcile variant spellings which have crept into my taxon lists from a range of print and electronic sources, and have arrived at mainly (exlusively?) algal families cited as ending in -ataceae in some sources vs. -aceae in others, for example Skeletonomataceae Lebour, 1930, cited in Round et al. "Biology of Diatoms", 1990, vs. Skeletonemaceae (present usage in AlgaeBase and elsewhere), both the same taxon based on the type genus Skeletonema. There are also some 20+ other cases including (e.g.) Acanthocerataceae, Borzinemataceae, Dicranemataceae, Gomphonemataceae, Goniodomataceae, Monostromataceae, Myrionemataceae, Nemastomataceae, Neonemataceae, Pascherinemataceae, Phragmonemataceae, Pleurosigmataceae, Pterospermataceae and more, from a range of sources, seemingly all algal families so far as I can tell.

I cannot find anything in the most recent botanical Code supporting this type of formation of family names so was wondering what the basis might be and whether there is any reason not to go with the shorter form as correct. However the "long form" is definitely still in circulation as a search of Google scholar will attest, example: 


On the other hand there are adjacent families - for example Thalassiosiraceae in diatoms, close to Skeletonem[at]ceae, seemingly never encountered in the "longer" format.

I was thinking that maybe it might depend on the original spelling as proposed, and whether mandatory corrections may then apply or not. Any advice (particularly from algologists maybe) would be appreciated.

Regards - Tony
