Description
Apex psilocharoid, convex, with cellular apical ends enlarged, generally shaped into a cap without apical nodules; in ornamented species (occurring as fossils) apical tubercles present, similar to those of lateral parts of gyrogonite. General shape of gyrogonite ellipsoid to cylindroid, sometimes very elongated. Basal plate pyramidal, its thickness being more than half of width. Size small to medium. [A great number of species were designated formerly under the name Chara without any real taxonomic significance, meaning roughly Characeae or charophytes.
