Komvophoron Anagnostidis & Komárek, 1988

Holotype species: Komvophoron schmidlei (Jaag) Anagnostidis & Komárek

Original publication and holotype designation: Anagnostidis, K. & Komárek, J. (1988). Modern approach to the classification system of cyanophytes. 3. Oscillatoriales. Archiv für Hydrobiologie, Supplement 80(1-4): 327-472, 35 figs, 13 tables.

Description: Filamentous; filaments (trichomes) solitary or agglomerated in clusters or in fine, mucilaginous colonies (mats), straight or slightly waved or arcuated, moniliform, simple, short or (rarely) long (to 650 _m), without firm sheaths, sometimes with very fine, diffluent, colorless, narrow mucilaginous envelope (staining !); trichomes deeply and widely constricted, not attenuated towards the ends, with indistinct motility (trembling). Cells more or less spherical or barrel-shaped, up to 10 _m wide, without gas vesicles, sometimes with irregularly dispersed prominent granules; end cells rounded (subg. Abyssophoron) or with conical outer cell walls (subg. Komvophoron). Cell division perpendicular to the longer trichome axis, cells grow into the original shape and size before the next division. Reproduction by dissociation of trichomes without necridic cells; trichomes dissociate regularly Å in their middle after they reach a distinct length. Hormocytes germinate at both sides (isopolar). Mainly benthic species, living solitary or in fine mats on the sandy or muddy bottom of unpolluted lakes, pools, small water reservoirs and streams, in metaphyton on plants, rarely in plankton (particularly tychoplankton). Two species are known from thermal and mineral springs, one is endogloeic (grows in the mucilage of other planktonic bluegreens). Distribution not well known; different species have probably the limited ecological demands and areas of distribution.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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