Holotype species: Cyanidioschyzon merolae P.De Luca, R.Taddei & L.Varano

Original publication and holotype designation: De Luca, P., Taddei, R. & Varano, L. (1978). "Cyanidioschyzon merolae": a new alga of thermal acidic environments. Webbia 33: 37-44.

Taxonomic status: currently recognized as a distinct genus.

Most recent taxonomic treatment adopted: Yoon, H.S., Nelson, W., Lindstrom, S.C., Boo, S.M., Pueschel, C., Qiu, H. & Bhattacharya, D. (2016). Rhodophyta. In: Handbook of the Protists. (Archibald, J.M, Simpson, A.G.B. & Samovits, C.H. Eds), pp. [1-45]. Cham, Switzerland: Springer International Publishing.

Description: Oval to club-like unicells 1-1.5 ( 3-4 µm, sometimes united in a common mucilaginous matrix. Each cell contains one blue-green parietal, polymorphic chloroplast which has no pyrenoid, a mitochondrion and nucleus but no vacuole. Cells divide by longitudinal growth. Contains chlorophyll a and C-phycocyanin in a chloroplast bounded by a putative single membrane. Storage product is phytoglycogen, with similar enzymes to cyanobacteria.

Information contributed by: Modified from R.G. Sheath. The most recent alteration to this page was made on 20 Aug 2018 by M.D. Guiry.

Comments: Found in acid fumaroles in the Naples region and thermal springs in USA and Java. Can survive temperatures up to 56°C and extreme acidity down to pH 1.5. Three enzymes, which are typically located in peroxisomes in other related algae, are expressed but there is no evidence of microbodies.

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.

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.
