5—9 и broad, crowded, forming at the surface, in the central рог- 
tions, а pseudoparenchyma with irregularly 4-6-angled cells; 
cells of the filaments uniseriate or with occasional longitudinal 
or oblique divisions, the distal hemispheric or crescentic-discoid ; 
cells of the median and basal parts of the colony dividing freely 
in various planes and irregularly arranged, often only 3-4 и in 
diameter, angular or rounded, now and then aggregated in ovoid 
or botryoid basal lobes, the colony commonly showing at its base 
one or more free penetrating filaments; reproduction by the 
setting free of exposed peripheral cells. [FIGURES 4-8.]
