Holotype species: Bostrychiocolax australis Zuccarello & J.A.West

Original publication and holotype designation: Zuccarello, G.C. & West, J.A. (1994). Comparative development of the red algal parasites Bostrychiocolax australis gen. et sp. nov. and Dawsoniocolax bostrychiae (Choreocolacaceae, Rhodophyta). Journal of Phycology 30: 137-146.

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.

Description: Plant colorless, minute (up to 2 mm), multiaxial, with uninucleate cells, parasitic on Bostrychia radicans. Tetrasporangia superficial, 19-27 by 12-15 microns, cruciately or tetrahedrally divided. Carpogonial branch 4-celled, the supporting cell serving as auxiliary cell. Carpogonium fusing directly with auxiliary cell. Gonimoblast filaments sympodially branched, producing terminal carposporangia 29-35 by 12-15 microns. Mature carposporophyte having large central fusion cell. Spermatangia produced by successive divisions of cortical cells, arranged in clusters. Division of germinating spore producing small lenticular cell and elongate germ tube containing cytoplasm of spore. Conjunctor cell cut off from germ tube and fusing with tier cell of host. Following fusion, parasite developing into small cushion with multiple pit connections to host.

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.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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