Description: Thalli encrusting or epiphytic; multifilament hypothallium of ascending and descending filaments, parallel to substratum; strong tendency to be "leafy" in habit; epithallium 1-7 cell layers, minimally photosynthetic; meristem intercalary below epithallium, photosynthetic; growth (cell division and elongation) occurring only in meristematic cells before formation of transverse cell walls, but not in a strongly defined band (no meristem split); double mode of calcification absent; all conceptacle primordia developed directly from intercalary meristem, sunken at maturity; sporangia bearing columnar cap walls (i.e., conceptacles multiporate), roof exposed by sloughing-off overlying epithelium; conceptacle cavity calcite, including surrounding and underlying perithallium dissolved by maturing sporangia; roof of spermatangial conceptacles not reformed by lateral growing in of tissue; spermatangia produced from columnar cells clothing entire inner wall of conceptacles.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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