| Type species: Komvophoron schmidlei(Jaag) Anagnostidis et Komarek 1988. | ||||||||||
| Descriptions: Komárek (1992): 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 (up to 650 um), without firm sheaths, sometimes with very fine, diffluent, colourless, narrow mucilaginous envelope (staining !); trichomes deeply and widely constricted, not attenuated towards the ends, with indistinct motility (trembling). Cells more or less spehrical or barrel-shaped, up to 10 μm wide, without gas vesicles, sometimes with irregularly dispersed prominent granules; end cells rounded (subg. Abys- sophoron) or with conical outer cell walls (subg. Komvophoron). |

| Reproduction strategies, life cycles, cell division: Komárek (1992): Cell division perpendicularly to the longer trichome axis, cells grow into the original shape and size before the next division. Reproduction by disintegration of trichomes without necridic cells; trichomes disintegrate regularly +/- in their middle after they reach a distinct length. Hormocytes germinate at both sides (isopolar). |

| Ecology, ecophysiology, ecological significance: Komárek (1992): 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 planktic cyanophytes). Distribution not well known; different species have probably the limited ecological demands and areas of distribution. |
