According to ING, "Greville (Algae Brit. 49. Mar 1930) stated that Asperococcus was 'created by Lamouroux expressly for a plant which he erroneously conjectured to be Ulva rugosa of Linnaeus....' Lamouroux (l.c.), however, also published and illustrated A. bullosus." - (29 Aug 2011) - M.D. Guiry
Description: Plants membranous, saccate, cylindrical to irregularly inflated, yellowish to medium brown, up to 1 m in length, polystichous by diffuse growth, attached on the substratum by a small disk, composed of inner layer consisting of large irregularly shaped large colorless cells and cortical layer consisting of smaller pigmented cells. Each cell contains several disc-shaped chloroplasts with prominent pyrenoids. Unilocular sporangia formed projected on the surface of the thallus in sori, accompanied by phaeophycean hairs and several celled paraphyses, obovoid. Unispores develop into fertile or sterile microthalli which directly form macroscopic thalli on them. Microthalli resemble Hecatonema and Ectocarpus in morphology (Kylin 1934, Pedersen 1984). Sexual reproduction unknown.

Numbers of names and species: There are 43 species names in the database at present, as well as 22 infraspecific names. Of the species names, 8 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.

Verification of data
Users are responsible for verifying the accuracy of information before use, as noted on the website Content page.
Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
