Methylation and spectroscopical analyses of DMSO‐LiCl‐solubilized fractions of the fibrillar cell wall of Coelastrum sphaericum Näg. established the presence of cellulose and β‐1,4‐linked mannan. A small proportion (2–7%) of (1→2) linkages in β‐mannan that introduced an interruption in the regular ribbon chain conformation was interpreted as a component that modulated the mechanical strength of the cell wall. The trilaminar layer fractions consisted mostly of algaenan and cellulose. Evidence for ether linkages between glucose C‐6 in the β‐1,4‐glucan and algaenan was obtained.
